My 86 fiero 2m (4cyl,auto,stock) is getting to much gas, which in turn is causing it to accelerate terribly. it hesitates and jumps. getts better when going faster. air filter is clean.Any suggestions??????

anyone???
No one has any idea what the problem is?

Not specifically, no. Sorry. It sounds like it's time to take it to a shop that has a good electronics guy. You either have an injector hanging open or too much fuel pressure. It's worth the fee to have an expert diagnose the problem.

i heared a couple of other possible solutions...
02 sensor
vapor canister
fuel return line

[farewarning]

Try changing the Egr valve that might help somewhat. Is your car reading any codes?

i have a 2.8 v6 fiero SE 2M6 rebuilt
The only after market parts are
auto light platnum tiped plugs,
Megafire distributor chip,
excell injectors.
i rewired the harness with bigger gauge wire 10 gauge. i put all new gaskets distributor rebuilt, with new coil,split fire wires.
when i try to start the engine there is no spark no feul preasher. There is no engine light when i used my code scanner on acsesorys. Only light that is on my dash is jar. there is power to the harness, the feul pump works with an external power suppliy that i used. I changed the coil both dont deliver spark to distributor. Anouther thing is that the computer itself gets warm. not shur what that means.
