Anyone know a good mechanic in the Roanoke area? Need some help on my 94.

What do you need help with? For most things around here I really like Brandon Automotive.

Kind of a long story. I did a trans swap, auto to manual and everything went well. The swap included a change to a new ECU.

After about 100 miles the idle began to act up, racing and revving if the clutch was out, but strangely acting normal if the clutch is engaged. My initial effort was to chase the vacuum system and I ended up replacing most of it (PCV, Evap canister, solenoid, lines, capped trans kick down).

The problem didn't go away so I replaced the IAC and TPS. Still no luck so I ended up redoing the other FI sensors (MAF, IAT, ECT and EGR components).

Now I'm getting some idle issues and a when accelerating it revs nice to about 1800 rpm and then feels like it's lagging until about 2500 rpm and then it revs freely. Also get CEL if I use the AC.

So at this point I think I need a new set of eyes that can diagnose and get me sorted.

Thanks, Tom

Problem solved!

I wanted to thank Duane and the guys at Brandon Automotive. They took a look at my truck and although they didn't solve the issue they were more generous with their time and advice.

With Duanes's help we determined that it was most likely a bad PCM. I ordered a replacement from RockAuto and installed it. Success, the issues are gone and the truck drives great.
