four cylinder problem
My 91 2.3 four cylinder runs smooth, then acts like it is running on 2 cylinders, then runs smooth. I have changed plugs and wires, but this did not fix the problem. also, check engine light goes on and off at different times. Any ideas??

I do not see anything that says technical info thread. I guess I don't know what to look for. Is there someplace I can find out what things mean, like MAF. I am so new to this internet search stuff. I appreciate any help.

the MAF stands for Mass Air Flow. it is a sensor that is mounted on the air tube right next to the air filter box.
pull the codes and check the fuel pressure first, like ken said, before messing with the MAF sensor. after you click the link above, look for "Pulling EEC-IV codes" about halfway down the page and click on it.
by the way, what plugs and wires did you put in?

which were the KOEO/continuous memory and which were KOER codes. you want to start with the KOER codes first in order
ken has pinpoint test for them, just inquire.

18 = Bad tach signal
28 = not a valid code for your truck
32 = EGR code, bad EVP or EVR
38 = not a valid code for your truck
88 = A4LD converter clutch override solenoid
98 = KOER code, did not pass KOEO test
You should run the pinpoint tests for the codes before replacing components.

I will re-check the codes tomorrow. I drove the truck around town today and it ran smooth. If I was working on my 1960 Austin Healey, I would be looking for a loose wire to the coil or points. I have checked all connections and they seem tight. I guess I am looking for something simple, because it is an intermittent problem.

I cleared the codes last night and rechecked them this morning.
This is the codes in order.
18
28
31
88
I don't know if it matters, the problem is on my 91 Ranger, standard cab, 5 speed manual transmission.
Any ideas.
