Hey guys, just finished my 350 tbi swap-in, in my '92 RS(stock 305 tbi). I changed the ESC module, Knock Sensor and put in 350 injectors like your supposed to do. I had a chip made for the car, and I took off the smog sh*t. Checked the timing and I'm at 0. I put the car 8 degrees advanced, 'cause that's where it ran the best without backfiring through Throttle Body or exhaust.

These are the modifications I made to the 350
EXHAUST:
- Hooker Headers w/ 2 1/2in collectors.
- 2 1/2 exhaust: y-pipe, and exhaust with a 80 series flowmaster.
- Eliminated C. Converter
IGNITION:
- MSD Coil, Cap, rotor, and distributer.
- Taylor Spiro Pro 8.8mm wires
- Splitfire Plugs
Replaced entire cooling system (rad; fan; hoses, thermostat. ect..)


Now, my question. Why am I idling at 1700 RPM?
The car runs like a raped ape, great throttle responce, very quick.
I check and no vaccumm leaks
The check engine light flickers with the idle of the car (brighter & darker)
I replaced the throttle position sensor, it didn't do anything.

I was told that possibly I didn't have enough backpressure for the O2 sensor to operate correctly so the car goes in a out of loop.
What the heck does that mean, and is that my problem?
I'm not real knoligible on the computer stuff, so this is not my specialty. Any ideas would be greatly appreciated.
Thanks.

i'd look at the iac and tps, if you can do it with a scanner all the better. you might alos want to look for any mechanical problems, like the stop screw too far out or binding problems i nthe linkage.
