I know there are many threads dealing with the same subject, but i did not find any resolve to my problem..
So, my 2,0 156, has some serious laziness in it..
I have already changed MAF, and lambda, i also changed the intake pipe from MAF to throttle body, as the old one seemed to be ripped.
No changes to the cars behaviour..
Its like, i dont have ANY power under 2900rpm, then it starts going better, but still there isnt all of the power from factory, maybe 120hp
It goes normally with half a throttle, but when the pedal is in the floor, it doesnt make any difference compared to half a throttle.. The car idles well, when on hot engine the idling may sometimes be a little high.
Maybe it misses a tooth on timing?
Timing belt is changed about 10000 km`s ago, and after the change it worked really well.
We did rebuild the whole engine again, as we bought the car as engine faulted.
I tried to spray some starter pilot to the intake parts, to see if it leaks air on somewhere, but didnt find any leaks.
Is there some tests that i can do without diagnosis programs? I have read the fault codes, but there wasnt any codes suggested to the problem, excepting the code from the lambda, i checked the parameters and the lambda was dead on there.. So i changed it after that, now its good on parameters too!
All the help would be appreciated!
