i have a crappy car. i have no codes now, that is a first in over 8 months and everytime there are multiple codes and different everytime too. even when i did nothing to fix it. would this be a bad computer. i am starting to think i have a faulty computer. no codes now finally but still running poor. the car was wrecked into a bayou but only the rear end went in so it got sand and water in the tank. i changed the fuel pump,filter,injectors,plugs,wires,coilpack,IAC.TPS,fuel regulator. all of those but the wires, 1 injector,filter and plugs were spares i had. the fuel pump came from a 91 5.0 tbird. while the injectors were out i half shafted the TB and ported the lower and installed new gaskets. right after it came out of the bayou it ran half ass but now it runs much better. now it still has a problem. it misses at part throttle but at full throttle, it really misses. this is all when the motor has load on it. when at idle it seems fine but you can feel a little miss. i still have not checked the fuel pressure of the pump that i put in it, i know it woke my car up since the old one was only pump 28 psi. i tried to find vac. leaks with some propane but nothing and i ran out of starting fluid too soon to tell. what do you guys think.
