Alright, I just made a 4 hour drive in my car and on top of my current problem of idling out and dying when I stop at a stopsign, when Im on the freeway and take my foot off of the gas, I shoot flames.
Great Tailgater deterrant. Also great for possible arsony charges.

This is a 2.8 manual 4 speed. ICM, pickup coil, dist cap and rotor all replaced about 2 years ago.

Speed sensor replaced about a month ago.

Code 24 and 32 come on in mid drive and car starts acting funny, however, it does this even if SES does not come on sometimes.
Code 32 has been on since I bought it.

ALSO

I have a sway in the rear when im driving at freeway speeds. Any help appreciated!!!

First guess on the flames is that you have a hole in your exhaust somewhere that is large enough to let in enough air to reignite the exhaust. Considering it happens off throttle I would inspect every inch of the exhaust tubing for a hole, which would be large enough to easily see.

Wow! I thought those women were screming for me,(James Bond Lives)!....If you have a pin hole in your fuel pressure regulator, unburned fuel will enter the exhaust and flame or boom (back fire).You will need a fine pointed punch to tamp down the center pins, unless you can find the correct security tool.

Second the rear toe. My fiero was erratic on highway above 50mph, and I straightened my rear toe (I had almost 1/2" toe out based on my readings) and now it seems fine at 65-70 mph, and lane changes are no longer an adventure. Planning to get it to a shop to get a good 4 wheel alignment after seeing what a difference just my "DIY alignment" made.

I had an alignment about 6 months ago, because I thought that was the issue also. I havent had much highway time so it was hard to realize that issue was still around. About 2 years ago I hit a guardrail and had to replace my control arm and all that stuff.

But also on the flames part, would this be causing backfires also? i had a cracked exhaust manifold that was "repaired" last year (lets not go into how bad carolina speed shop messed up my car), but I feel as if the issue may be back due to a clicking noise on accelleration.

Please explain exactly how that works ... how a leak in the FPR somehow introduces fuel directly into the exhaust system.

You haven't told us what year Fiero you have. If an '88, it could be that one of the long bolts that attach the lateral links to the rear knuckle have loosened. This is a common problem with '88s.

Ha Ha and you think this is a bad thing? lol Just kidding Rednecks around here pay alot of money to put ignitors on their pipes and a bottle of propane tucked away with a NO2 solenoid wired in. As far as Tailgaters? theres a 20ft margin of safety/Fun .

Was your fan not working or low on water? I use the std front fan but also another one underneath pushing its thermo activated . also attached under the Hatch vents im installing 2 10 inch fans that are also thermo activated from inside the engine bay so i can purge the engine bay at a set temperature.
