91 gts-t rb20DET sticking and misfiring

[katecarlson]

My skyrine is driving me nuts. It is sticking and stalling and misfiring. Even after I have warmed it up and everything. Sometimes when I start it, it will just idol at 2k. Then sometimes when I start driving it will idol going 1k-2k and back and forth as if I was pumping the gas. If I gear up when it is misfiring, it stops. But it randomly just starts slowing down no matter how much I have my foot on the gas. I have changed the fuel filter, a coil, the o2 sensor, the spark plugs, cleaned the MAF (found a piece of loose solder, which I thought was causing a short, and causing the problems but apparently not.) Help

If a piece of solder came off the maf i would bet you have bunk connections in it. Try borrowing one to see if that fixes your problem or you can open it up and try re-soldering the connections in it.

I'm thinking it might be the CAS. I had a similar problem with no throttle response. I ended up changing the cas to fix that. Then I ran into limp mode problems which I had to change the mafs to fix that problem. Check out my threads it should help you out

My cars engine idled at 1500rpm when cold, hot and was MAF related (failed), as had MAF error code on ECU. Replaced MAF, problem solved.
