mot fail due to immisions but i cant figure out the fault - Astra Sport and Astra Owners Club - Mk1 | Mk2 | Mk3 | Mk4 | Mk5 | Mk6 | Astra Van | 888 | VXR

took the project car for an mot today but i cant figure out the problem, the immision where so high it was rediculas ive never seen a car so out but there is a problem with the car, when cold it doesnt like the 1.5 to 2k mark its judders and jerks so bad you cant drive it but if u go past that mark its perfect. Once the car is warmed up its much better but there is still a slight problem. Has anyone had a similar thing its got to be a sensor or something but which. Its a catch 22 really as the engine has been stood for 2 years and really needs a goo thrapping to clear it out but i cant do that as its not mot'ed or taxed so i cant win.

what engine is it?

Jace · 20-08-2005, 00:30

sounds like you need to clear it's throat, what about taking it out on your private track in the early hours?

killer_astra · 20-08-2005, 02:41

Does sound like you really need to give it a good run.. thats the best and cheap possible way of trying first.. what happens when you've reved for a bit when its idling? Does it go normal again or is it normal only once its warmed up?

how many miles has it done mate? if its not to high you could try that 10K boost from eco tek, just a sudjestion

its a gsi turbo z20let conversion we have done the engines has only done 2k but been stood for ages since it was last ran. Its very bad when cold and you cant drive slow i.e u have to nail it to go past 1.5-2k or its horrific and undrivable. Ive loaded it today with 4 bottles of different engine cleaners and immision liquid i.e redex but the unbranded stuff we get and it seems to have made a huge difference. Its a perfect engine when its at 80-90 the only thing ive found its its guzzling fuel i cost me 20 quid to do 50 miles today but there was a lot of idiling to let it run and clean through. We also hade a lot of white smoke when u blib the throttle but that also seems to be dissapearing. i wondered if an ecu reset would help or maybe take it to vaux for them to remap the ecu but the only issue there is i cant until its moted.

thanks for your help keep it coming.

i know your allowed to drive to and from an MOT without tax but not sure if you can to repair it, would have thought so, otherwise how would you get it fixed for a re test?

ben lee · 20-08-2005, 23:03

sounds like the coolent temp senser maybe faulty (running cold start map all the time so over fueling)

mitch@evolution · 20-08-2005, 23:51

i know my intercooler sensor doesnt work as it wont idle with it plugged in ill check the coolent temp sensor, anyone got a pic of which it is so i can order one and try it out

mitch@evolution · 21-08-2005, 21:44
