I recently put in a 288 catacam and head work. My engine was originally a Hartge H26 but the cam was wiped and the egine was a little tired, as the head was already worked by Hartge, is was more of a clean up and and not a crazy port job.
PROBLEM: the car doesn't seem to idle properly, when I come to a stop it drop to the point is almost stalls, and the idle seem really rough(like a mustang with engine work), the car was running lean, so we adjusted the AFM so it gives more fuel and I put a O2 sensor from a 3.5 so it would run richer. The plugs aren't white anymore but the idel is driving me nuts. I even bought a new idle control motor just in case.
Do I have too much cam, if so how is it hurting performance, the car seems to go well, I do 195km in 4th and top speed so far is 230-235KM.
I was doing those numbers before when I had a cam that was completly wiped and a head that was in need of some TLC.
ANY IDEAS AND COMMENTS WELCOMED.
Thanks
