Stumping all the 3800 guys...

Hi 88FieroGTS. I have a 3800sc in my Fiero that I put in last spring and the harness and PCM tune were done by Dan in Canada (fieroflyer) probably the same guy as you. I get a flashing check engine light at times but my big issue is I'm getting no oil to the ac comp. side lifters. Obviously doesnt have to do with the tune. Once that's figured out ill be scanning the PCM to look for codes.
 


Hey Lou, yeah I've seen you on PFF.

So, I still have the issue - It feels like the TCC is getting stuck on, usually when you get on the gas to pass someone, it'll disengage but mine chugs along, until I either let off and get back on - Or, if I hit the brake to disengage the TCC.

I also have a misfire still, Been noticing my plugs keep getting cracked.
 
im with bill on this, my car was a pain in the a** was from when i made header extension crossed 2 wires, didnt know but afr and o2 voltage sorted that out, aeroforce showed it run fine for 30 seconds then it was all over because it goes open loop, check voltage on 02 should be 200-900 iirc
 
My voltage reads fine throughout driving.

Hits 90-100's when letting off throttle, bounces up and down consistently.

Just the mileage sucks now, and the TCC doesn't seem to want to disengage when trying to pass someone (I have to manually release it with the brake. Even then it pops back on)

I noticed cruising around 50-55, if I get on the gas a little more it'll kind of drone down and chug, pretty much simulating the TCC locking up and I again have to hit the brake, or get off the gas and get back on it.
