I have just taken delivery of a very pretty Tamora with a T350 nose conversion (for pics see my previous thread) After collecting the car yesterday I have few issues... although I know there is a great car trying to rise above them!

Headlights are awful but are marginally brighter when I flash the lights as all four lights illuminate briefly, I have seen Osram bulbs recommended (do these replace all four bulbs?) or can I change wiring to keep all lights on permanently whilst on main beam?

Car baulks quite badly going into 5th gear until it gets really warmed up after about 50 miles. It doesn't make a noise, just feels very restrictive going into gear.

I slide around in drivers seat, I need to have a partial retrim anyway - can the side bolsters be enlarged to provide better support?

Anyone know where I can get a replacement boot strut as the one fitted doesn't support the bootlid at all? The seller says it is easier to get the roof in without a strut fitted at all?

Drivers seatbelt sticks

Radio reception doesn't exist, so I bought a CD and the Alpine head unit ate it!

Two warnings come up when I start the car, the first is the outside air temp sensor apparently, cant remember the other!

Finally the biggie, when I bought the car I knew it had a slight missfire below 3k rpm but the engine was rebuilt and as it ran smoothly above this I wasn't too worried, but on the way back it has got far worse and is now through the whole rev range - even making driving uphill on the motorway an issue, I'll book it into my local TVR chap and keep my fingers crossed...

I hope I haven't bought a pup, time will tell. Any advice appreciated!

The misfire sounds like the ignition coil on it´s way out or ignition leads. Both not expensive to fix. Have it hooked to a Laptop and have the throttles adjusted. I cannot imagine any Major engine Problems causing a misfire. A misfire can cause major engine problems, though. Have it fixed...
And of course congratulations to your new p&j...one cannot make serious mistakes with a Tamora, though the front conversion might be a question of personal taste.

All the best,
Björn.

5th is a known weak point in the T5 gearbox, see my post for my ex fifth gear. I would suggest you keep it in 4th before you have your TVR guy check it out. If its shot you are looking at around 800 quid.

Looks like you have a few wire and sensor faults etc rather than major engine faults.

The misfire defo sounds like the coil pack, pretty cheap part to replace.

The temp sensor fits in side the nose cone on a "standard" Tamora, as yours has been mucked around with, the sensor has either been disconnected or the wire might have been chopped? I take it you know how to override the warnings with the steering wheel paddles?.

The misfire, is it on small steady throttle openings or on acceleration?
Throttle bodies the former, coil pack (from a Vauxhall V6) the latter. Common problem.

5th gear, had the same on mine, mine even jumped out of gear a couple of times on the M-Way, i was very lucky, the centre console was stopping the proper engagement, i physically forced the console foward just a few mill, and job done. Hopefully you might be as lucky??

Cant remember the other niggles, so hold on i will be back.

Sliding around, not sure if you have full leather,(looks nice but your arse slips around) if so, change to the alcatara (sp) seat bases when you get a retrim, never had this problem though, must admit, the seat holds me in nice and tight.

Seat belt, TADTS, especially if the car is not on completely level ground.

Boot. There is a well known mod you do, with washers on the strut, this makes the boot open further and helps getting the roof in ,from impossible to hard.

Radio reception. New one on me. Can only think that the aerial is disconnected?

"Shep" might be on later, what he don`t know about the Tam ain`t worth knowing.

Thanks for the reassurance chaps. The missfire is on acceleration, initially only below 3,000 rpm but now throughout the rev range. I'd like to drive the car to a couple of trimmers to get quotes before handing it over to my TVR man. I don't suppose driving it another 20 miles will do any long term harm?

The seat base has been changed to leather fairly recently, but the door cards and roof lining are Alcantara so I may change to that, but I am slim and could really do with bigger bolsters - I'll ask the trimmers what can be done.

first thing i would try about the misfires is taking out the airbox and see if all leads are well connected to the coil pack and that the contacts are free of corrosion. And take a look at the 4-pin plug, too.

I've had misfire problems and it turned out to be the leads to the injectors. Remove them one at a time until it doesn't get worse! If you need to you can spur 1,2, 3 or 4,5,6 together as they batch fire anyway. If that makes no difference, repeat the remove and test exercise with the hT leads until it doesn't get better to isolate which isn't firing. You can remove the plug and check its condition and sniff for petrol to confirm things.

Hiya i love that Tam its the front TVR should have fitted imho, welcome to the world of new Tiv niggles, they really seem to play up under a new driver.

As above seat belt always seem to lock try to pull it all way out and let roll back several times.

5th gear is sometimes clutch, does it baulk going into reverse as well?. Centre consuls do move so try pushing it back.Also sometimes the rubber gaitor covering underneath gets all bunched, other possible cause is reverse switch has gotten pushed to far out and maybe actually stopping full movement.

Radio is always crap, check cable is connected your car has had major works and alignment on dash is a pain(bolts on my old one were not screwed up tight at all).Try pulling fuse on cd player and refit sometimes reboots.

The seat issue can be sorted, as you already have alcantara on cards etc why not have seat cushions trimmed on one side with alcantara and leave other side leather.then you have choice.

These niggles will all calm down and you will enjoy your pocket rocket, I had mine apart so many times so pm me if u get stuck
cheers Geoff

I would go for coil and ht leads to sort the misfire - Make sure you get a proper Bosch coil pack not a generic. For the ht leads go for the std black tvr ones tried the upgraded ones they were ste. Vauxhall parts world for the coil pack its an omega v6 about £80 inc vat! Common problem don't panic just yet

Radio is naff most of the time i gave up and use my iPod

The seat belts do stick on the slightest of slopes TADTS - on mine it's the ps side drivers is ok

Boot strut - google the part number on the side of the strut they are about £25 make sure youngest the correct load rating if they are over rated you might damage the strut mount points (same problem with chims apparently) if the boot opens too far it pushes on the hood and marks it.

HID lights will fix the poor illumination issue - 5000k 35w (H4 is the fitment for the tam) if you start going higher on the wattage and k value for the lights it looks a bit 'max power'

Synchro on 5th might be going but do you know when the gearbox oil was last changed/checked?

The trimmer should be able to sort your seats tell them what you want and see if its possible. the bolster had collapsed on mine which made it a little less snug! there are plenty to pick from, i recommend Adrian at central tvr but there are plenty of good ones like D&C in Blackpool or Dave the trimmer near me in Milton Keynes

Regarding the fault codes, the ambient sensor reads bks most of the time anyway! The other code might be important - if it's #4 EFI fault it might be related to your misfire you need to plug it in to the diagnostics to check what faults

Thanks Shep. The seller of the car is sending down some leads he had on order and if that doesn't work I'll try a coil pack - how many are there? I think some cars have one per cylinder...

I'll buy a new stereo with an ipod link.

I've taken the car to two local trimmers (I live on south coast) but neither could identify the pale coloured vinyl, I will try some TVR specialist trimmers to see what they suggest.

The car has a T350 nose and lights, does anyone know which uprated bulbs will fit? I guess they are different to those in the Tamora?

I would go for the Alpine BT136 head unit. It's dab+ & Bluetooth for phone & iPod it also has cd.£250 ish with a dab aerial. The coils are not separate you have to replace them all as a 'pack' its under the air box held on with 4 bolts. Make sure you seal the plug cover down when you change the leads - water can and will leak down the plug holes which can cause a misfire

Thanks, I'll investigate.
