Hi everyone,
Dont know if anyone would know,
I put a 3 inch short ram intake in my gf's 89 prelude and knocked off all the plastic, space taking non-sense in the engine bay. Whilst doing it, i chucked about a quarter of a can of throttle body cleaner (dont think it was ever cleaned before judging by the amount of gunk dripping out) into only the throttle body. Since then, when the car warms up to operating temperature, the idle fluctuates between 1,000RPM and 1,500rpm at a slow-moderate speed only in Park and Neutral and it's fine during any other gear. I also changed a few of the vacuum hoses to silicone due to the warn out hard rubber ones. Can anyone suggest what may be the issue?
thanks
andy
