First service problems arhhhh
Discussion
Hello,
My chim 400 just been in for it's first service under my ownership and I have been given a small list to do so I'm looking for advise.
- Radiator the fins are shot at the bottom would it be best to replace or would anyone trust a recore.
- Running lean in fact so lean to quote the mechanic "never seen a TVR like it". Apparantly the airflow meter is faulty. Ive checked with the bible and the voltages mesured are within range but on the high side but in range. I have seen posts on the AFM's and faulty ones tend to run rich so I'm looking for an alternatives suggestions to before I purchase a new AFM.
That's all not bad considering it's done 42000

With the radiator it's just the fins are rotton and missing it's not leaking.
I run the car on shell optimax or esso high octane stuff if this is what stealer means I'm new to this you terminology you see . I didn't get a quote cos I'm a bit pushed for cash at the moment. I'm pretty handy with the spanners so I thought I will do myself and have it proffesionally tuned later.

Running lean could be that the injectors are 'gummed up' and need cleaning.
Austec did this on my Chim 400 a while back (at about 42000miles) and it improved the running of the car quite a bit...It's not cheap, but might be worth looking into. They hooked the ECU up to the diagnostics on their rolling road and found that the electronics were all OK, but that there didn't seem to be enough fuel being injected...
Hope you can get it sorted without too much expense....

Edited to add that if you are handy with spanners you should be able to remove teh injectors and use a postal injector cleaning service usually £15-20 per injector - I used HGL Motors... hglmotors.com for my 205 GTI, but let Austec deal with the Chim.

Thanks Alex and Andy.
Andy thanks for the offer I live in Stoke which is a bit far. I'm going to the local club meeting next month to ask around. By the way Andy looked at your profile your car is very similar colour to mine I will post mine sometime.
When the car was serviced it was very cold and wet would this have made a difference?. It's just that it goes very well so I'm woundering if it's a one off.

what are you getting, roughly, MPG wise???
Mine was running unbeleivably rich a few months ago, 6-9 mpg...the ecu was shot!!!
If you are getting approx 200 miles per full tank then dont worry too much...it seems to be roughly the norm.
What condition are the plugs?
What are the emmisions like and are the lambda sensors ok???
Can you hear the fuel pump whirring away constantly?
Theres a couple of things to look at.
Failing that wait for Greenv8s, he is good at this sort of thing!!!

I'm getting around 200 mile on a tank it may be a bit more only use it at weekends. With the weather of late it's only done about 10 miles since the service so I'm going to give it a good run and check the colour of the plugs when I have time. The fuel pump can only be heard when I first start the engine after that its pretty quiet.
