i'm throwing in the towell

[redmatt]

thats it now, i've spent today under and in the car again changed the fuel pump and the resistor pack on the wing, put back old leads ( they were fine before i changed them ) also took some advise from v8 developments and went and bought another rotor arm (lucas part ) still having the same problem put my foot down cuts out and then misfires ease up on the load drives ok, have no more ideas or patiance, some how ill get to a garage ( not many v8 people around my area )

Maybe it's the best thing to do Is there a Wedge friendly one near you?.I don't think it will cost a fortune to sort out.

Have you swopped the coil? Join the AA and let them sort it out for you It must be something simple just a pain to find it. AA are really good at this sort of thing.

[jmorgan]

Check your yellow pages etc. Turned out I had a V8 specialist 400yds (as the crow flies) where I used to live. Any TVR independants down there?

Don't give in.

[redmatt]

the one thing that i have not tried is the coil i will give that a try as one last thing then its the aa for me

Try Paul and his garage PMW on 01245496739

If you know Chelmsford at all it's near the new (-ish) Anglia University, on the grounds of the old Hoffmans site.

i know chelmsford well not that far away from me ill give him a call

Matt me old mucker: if you and I were about 200 miles closer together I would gladly pop over and fix the bloody thing for you.
Sadly, the closest I get is Leicester.

Not sure if you tried swapping the ECU from the other car: might be worth a try just to rule out dry joints etc.
I can pretty much guarantee it will be something really stupid and you will kick yourself when you find it.
At the moment I would relish the challenge, as opposed to the tedium of sandblasting and painting Lotus suspension parts, which I feel as though I've been doing since the dawn of time. Still, I know there's an end in sight, and once I get to pose around in the Esprit I'll soon forget about the grief, as will you once your car is fettled.

Do you have the early hall effect distributor with a white disc and ferrite rods inside the disc? They are buggers for failing at random. The later variable reluctor types with a star wheel are much better. Go for the coil or AA first!

I had problems wi mine parked up jus wud not start again well ***s*d off turned out to be the bit in the dizzy that wer busted.
I aint no mechanic but I had a cavalier sports hatch one time with similar problems started ran ok drove ok till you put you foot down then no power or revvs got a mate to av a look he tested compression and turned out Kam wer up the spout I hope yours isnt but symtoms sound very similar to that, but then again it is a wedge so it mite jus be the flubidestrum thats parted company from the thingymiwotsit an the first bump you go over it will rite fix itself

[redmatt]

my cap is def a star type cap, ive had allsorts today change the air flow meter and the coil and the coolent temp thing and the big one next to it will try all these sunday, thanks for the idea of driving over at least i know you guys care and thanks jamie you really made me laugh with some good ideas as well ill let you know the update

Redmatt when i had my 350 it developed the same fault put ur foot down and not much happens just coughed splutterd and died on u lift off and it would ok enough to keep going ,anyway after a bit of playing around it was simply the ECU that had packed up {not cheap but easy to replace}any way someone on this forum said they are designed if they do go wrong it wont pack up completly but leave enough fuel to get u home dont know how true this is though!

hi,

i had a very similar problem which i thought was electrics but after spending lots of money it turned out to be cam lobe wear, it does sound like a misfire but your find its blowing back out the air intake if it is cam problem you are having , best of luck.

When you get worn exhaust valves, you would typically get some frontfire back into the plenum which sounds dreadful.

The burst of exhaust gases back into the plenum also kills the accelleration.
If you try disconnecting each injector in turn you will eliminate the problem at the expense of only running on 7 cylinders, but it will tell you what's going on.

If this proves to help, the cam is quite easy to check, you take off the rocker covers and turn the engine over, look for rockers that aren't rocking much. start with the easy one on the driver's side, this has the rearmost cam lobe which is the most vulnerable to wear.
On the electrical side - swap out the temperature sensor on the inlet manifold (can cause overfuelling).
Another throttle-related problem could be a worn throttle pot track - I can recondition these for a tenner.

If I think of anything else to try I'll post some more.

[Boosted LS1]

If the cam has a worn inlet lobe won't the cylinder pressures be down? As for the exhaust lobe, would the pressures be higher on the effected cylinder?

[redmatt]

i will be working on it again on sunday was thinking of having a party (its a bring your own tool box party) followed by a fix me car party anyway will try the temp thing as others have mentioned it. the worn lobes and stuff would they be a progressive thing not a sudden thing as this happened suddenly?

Did you ever sort this out? Manage to get it wired up to a crypton tester or i/d the fault?
