Hi Guys
Needing some advice on a problem that is doin my head in!!!
My car was previously running perfect in stock condition.
Borrowing a loaner ecu from paul which has been homefried, most impressed with the power/torque increase, however it would missfire on full boost at first. It has been getting progressively worse over the last few weeks where now it feels like if ur driving steady off boost (vacuum on guage) say in 2nd or 3rd you can feel the power decrease and a constant missfire, not a violent missfire but a subtle one. The engine feels like it bogs down a bit.
When i do go to boost fully it feels like there is a lack of power even although it seems to pick up on the gauge ok. Other times it will start to missfire when in the early stages of boosting causing me to back off.
Changed plugs to the suggested BOSCH ones, checked boost pipes for obvious tears but nothing untoward found. Only part i didnt check was the intercooler o ring. If this is gone would it cause these problems?
Changed leads for known good ones of a 90 20v and same occuring. Just checked distributor cap and rotor arm, distributor spark point surfaces seem to be fairly black in colour with some kind of debris on the surface. Cleaned these up and look ok now i think. How bad to these points have to be to cause a problem?
Where can i get a hold of all the kit needed to properly test for boost leaks just incase i missed something?
Please any pointers would be much appreciated.
Thanks in advance for any help you can give me.
