Engine Mechanical problem
1992 Honda Prelude 4 cyl Front Wheel Drive Manual 375000 miles
Engine - H22a with JUN stage2 cams
ECU - piggyback with Unichip
Recently my RPM drops too low, abt 500RPM. It usually sits at 900RMP on idle. I brought it to a workshop and has check on my spark plug. All 4 of them are burned out completely. I have then changed them.
We checked the car again and the idleing is still at 500RPM and there are quite a lot of black smoke out.
This morning as I was driving off, the car has a silght "pulling" effect. It seems like there is something stopping the car to move smoothly as usual. And on the 1st through 3rd gear, the car does not drive as smoothly as it used to be. The exhaust is also coming out with a very low gurggle sound during low RPMs when driving off.
When I let off the throttle at abt 60kmh, I will feel the car having the same pulling effect.
have the same problem?
