KA24E Runs Really, Really Rich

[#1 Stunna]

Hi guys,

Picked up a 1989 SOHC Coupe a few weeks ago and the car has been running really rich. It will shoot out soot upon starting the car and have a strong smell of gas. The car sat around for over a year or so before I picked it up.

I seached around on here and found out that it could be the Engine Coolant Temperature Sensor or the Engine Coolant Temperature Sender. I originally replaced the Engine Coolant Temp Sensor first and it ran the same exact way, I then changed the Sender and ran a little smoother.

I had it on a smog machine and it only seems to be doing it at idle from what the mechanic told me. It will buck at low rpm's and run very sluggish.

Any help is greatly appreciated

A faulty MAF sensor can cause lots of problems including running rich and it very quick to check, turn off the car disconnect but don't remove the MAF then turn the car back on. The ecu will default to limp mode and the car will either do the same thing (not a problem with the MAF) or run alot better (problem with your MAF) try this then report back what happens.

Sorry for the late reply, I've been really busy the last few days.

Well I disconnected the MAF and turned the car on, the car ran for about 3-5 seconds and then just shut off.

So I'm guessing the MAF is not the problem. Next up I am going to replace the cap and rotor and see if I have any luck.

Any other advice is will be greatly appreciated.
