So Im trying to help a buddy out with his car. Maybe someone has some better ideas than us. The car starts, but idles at 3000 rpm and the check engine light is on. But when you push in the clutch, the idle drops to a normal 700-800 rpm and the check engine light turns off.
Hot or cold, in gear or neautral, the problem is always there. It has gt40p heads, 1.7 rr and gt40 tubular intake manifold. Its actually my old motor as listed in my signature, minus a few items. The motor ran great in my car, and it ran well in his for awhile. It has been sitting for about 4 months. He also got a reman A9L computer from late model resto and gave his old one away. Tried pulling codes but KOEO tests will not start, and cant do KOER test either. Verified that we have the jumper wire in the right place. His old computer only allowed us to pull KOEO test codes and thats it.
We've changed out his MAF for mine, both programmed for 24# injectors, and still nothing. It has a brand new IAC from a few months ago as well. Adjusted TPS to .996 volts, vacuum is good, timing is good. The only other thing Im thinking is stale gas, since its been sitting for so long, about 6 months ago since last fill up. But could this really be a problem? Havent added new gas yet.
Anyone got an idea let me know, thanks.
