hey guys, i have an 86 vandura with a 350 tbi. i need help, its a tbi, so hopefully you guys can assist. at first the problem was the car got stuck on us, and it wouldnt start. we changed the coil, distributor cup, rotor inside cup, and the ignition system inside the cup, sorry i forgot what its called. the truck ran ok after that, but everytime you would put her in reverse it would stall, then it started doing it in shifting into drive. so a friend came to take a look, he said the intake/tbi wasnt clean, so he took CRC FUEL INJECTION AIR-INTAKE CLEANER, and sprayed like half the can into the intake while the car was running. after that the car began to blow the ecm1 fues. it kept on doing that. so he said get a computer, we replaced the computer and the same thing is ooccuring. does anyone know if that spray cleaner can harm anything? does anyone know what the problem could be? any solutions? any help would be greatly appreciated, thanks!

It could be unrelated, possibly a short somewhere on the harness that carries power in that circuit. I think the esc also draws power off of that circiut as well. Its been awhile since ive looked at the wiring diags. Its also possible that the cleaner could have damaged the wiring by breaking down the insulation. Start by checking the wiring around the tbi and the surrounding area to make sure that especially the wires that feed the fuel injectors where not damaged. As for any future cleaning, the tbi and IAC should be removed and cleaned off of the car to get the best results. Its really the only way to fully clean the IAC and clean the vacuum passeges in the tbi.

 

my dad fixed the problem, it was something in the throttle body, and wiring. thanks for the help though... happy new yr.
