Hello all, I am new to posting here but have read countless threads. Cant seem to find a similar problem to what I am having so I'm hoping for some help.
I recently picked up a 1986 Fiero that was stored in a garage since 1999. 2.5 4cyl with 5 speed manual. Brought it home, sprayed some ether in the TBI and it fired right up. I've gone through and replaced fuel pump, filter, TPS, MAP, IAC, PCV, cap, rotor, plugs, wires, ignition coil, temp sensor, took apart the TBI and rebuilt it. Also replaced every fuel line, brake lines, rotors, calipers, E-brake cables, pads, bearings, shocks, struts, ball joints, clutch line, master and slave cylinder, and many other mechanical components and cosmetics that don't relate to my problem.
My issue is that I took it out for about a 100 mile ride and everything was fine except that it overheated when I was almost home. I have to still flush the cooling system but I'm waiting for the replacement radiator to be delivered. Now my problem happened after it overheated, so I was wondering if there is a sensor I'm overlooking that triggered and never reset? My issue is that the car starts just fine and will idle around 900RPM nice and smooth. As soon as I release the clutch is seems as if it is starving for fuel even if I work the pedal and try to keep the RPM wound up. The EGR seems to be fine, the plunger is nice and smooth. Fuel pressure is more than enough when I hook up the tester. I've checked the vacuum lines and haven't found any leaks. I even removed the catalytic converter and put in a straight pipe thinking it was plugged up but nothing changed. I'm at a loss what could be wrong. I was thinking maybe the charcoal canister is dirty, but when I remove the hose going to the TBI and plug it nothing changes. (EDIT) I forgot to mention that I checked the timing and it was slightly off so I set it to 8 degrees. I also forgot to mention the it is still throwing code 34 and 35 even after replacing the IAC valve.
Any help would be greatly appreciated, or just steer me to a post I may have overlooked. Thank you all so much.
