fuel problem ok i have a 82 crossfire EFI engine, the car runs fine, expect for the fact that it runs rich and everytime i let off gas it lets of an obnoxious pop almost like a backfire, it was cool at first but it just is getting really annoying. i was told by a friend of mine to change out the injectors i just wanted to make sure thats what it is first before i spend a few hundred dollars for the same thing to happen. thanks |
Is the SES light on? If so, get the codes the computer is setting. I'd look to O2 sensor before injectors. |
Re: fuel problem I'd also check plug wires, dist cap, rotor, plugs before injectors - ignition issue will cause backfiring. Are any of the plugs wet with gas? All plug wires & plugs firing? How long since cap/rotor/wires plugs been changed? How long since fuel filter change? What's timing set at? |
Re: fuel problem whats the SES light? i know the check engine light will come on and turn off every so often. it will only last about 10 seconds but i havent timed it. the plugs wire distributor and rotor are all knew i just never gaped the plugs forgot about it but the noise sounds like back firing, also i go through fuel like no tomorrow had a full tank now its at half now and i must have driven less than 10-15 miles maybe more granted i was hammering the gas but i think it to bw a little rediculas |

Re: fuel problem ok thanks also i pulled the wires plug and distributor appart it all seems fine expect plugs in cylinders 1 and 3 have excess carbon build up and the plugs are literally brand new maybe 20 miles. also cylinder 5 the plug is very clean, thats all i had time to get to tonight was getting too late and too cold. any reason why it might be doing that tho? |
Re: fuel problem ok iv try that method with the pin and it doesnt seem to work i ran a pin from 6-12 key off, then key on and the service engine stays on like it normally would. i also noticed that it the computer hook up for the car is square not offset, and also there is 12 holes but only seems to be 6 working holes the rest look as if for show or just there |
