Engine Performance problem
1992 Dodge Colt 4 cyl Front Wheel Drive Manual 260K miles

I'm working on my son's 92 colt with the 1.5 mitsu engine.
Engine died a week ago at which time I checked and no spark. I replaced it with a new/not reman distributor which has the coil etc built in.

Car fired right up.

Set the timing as per spec. With wire grounded.

Problem:
Rough/low idle
Hunts
While holding the throttle at @1500 the engine sounds like it's detonating. By retarding the distributor while holding the rpm I can kill the detonation noise.

Plugs are brand new just installed with 0 miles. Running for 10 minutes or so the plugs are sooty.

Compression is 175 on all 4.

Timing belt is not new but I checked all marks and they line up perfectly. Sooty condensatioin coming out of tail pipe.

No cracked hoses. It doesn't have an EGR.

Any ideas?

Thanks. John

John: Is there any smoke from the exhaust? Also, have you checked the temp sensor?
