88' running problems

[Tc387]

My 88 22re is having a few problems- on start up it runs fine, by after about 2 minutes it idles very rough. Also spits and sputters when accelerating, and the temp is unstable. I thought it might be fuel or ignition but not sure after he overheating problem. Any help would be much appreciated.

Go through all the standard stuff first then reply if they don't fix it.
1. spark plugs
2. spark wires
3. ignition module
4. engine timing
5. Fuel filter

check all these items if you need direction on how to check them consult the factory service manual, if you dont have it then you need to get it there are many sites that offer it free.

Could b tps sensor also

agreed but that was going to be after he checked the others along with MAF and Vacuum leak

Thanks, I grabbed a new fuel filter as it seems to be the Most likely villain at the moment- only problem is it seems like it's going to be a huge pain to get to it. Plus now my transmission is actin funky. I'm hoping it just needs some fluid rather than a new clutch.

Check out my thread here if the standard checks above pan out.

I'm guessing you have possibly burnt up your clutch, due to the issue you have. I just bought my T4R from a buddy of mine and between the two of us, the clutch in mine was DONE. Good luck

I know it sounds dumb, but check your idle screw, adjust it a little, that may explain the rough idle.

New fuel filter installed, same problems but a bit more tame. Fearing the fuel pump is going.

I also adjusted the idle screw after installing the new filter, and the rpms are much more acceptable. Unfortunately I just found a fuel leak so it's back to the garage.
