    I've had this problem for 4 months. I'll let you know what I've checked and done: I've replaced the cam and crank angle sensors with no change. I was told by a shop the valves were burned so I pulled the heads and had them rebuilt, no change. Timing shouldn't be a problem, its an old school timing chain. I don't want to say its impossible to slip, but if it did there are probably bigger issues to deal with first. A stretched chain the pcm could probably adjust for. Besides, the timing marks are internal so there is no way to conveniently check it. If you're confident the plugs, wires, and coil are good then you should check the fuel pressure. To low of pressure could be a plugged fuel filter, bad fuel pressure regulator, or weak fuel pump (unlikely). If you have gas in the vacuum line, the regulator is bad. I have no fuel pressure when I turn on the ignition but I hear the pump whirl up. The pressure is perfect when its started (for the 3.3 is 49psi w/vacuum, 55psi without). The second the ignition is shut off, fuel pressure drops to 0. I pulled all the plugs after running the car and found cylinder 1's plug soaked with gas. The wire ohms out, and spark plug tester shows its getting juice. I swapped the spark plug with another cylinder and the problem stays with cylinder 1. I believe mine is a fuel injector issue. I had them professionally cleaned but all the computer read out shows is flow rate and spray pattern... not if its stuck open, flooding the cylinder. I can also hear each one click when touched with a stethoscope. I'm going to the junk yard to pick up a couple injectors and see if replacing that one helps. Good luck!

    Also, I have no codes.

    and for codes 12 and 32:
    12 - Battery has been disconnected within last 50 key-on cycles
    32 - Open or shorted condtion detected in the EGR transucer solenoid circuit
    32 -Required change in air/fuel ratio not detected during diagnostic test

    His problem is with the EGR.

When cold starts but dies.to start, peddle to floor, rev a minute then it idles but at times dies when accelerating from a stop. Raw gas smell present and puff of blue smoke when it starts.


have you checked the cylinder compressions as backfire and blue smoke can be a symptom of low compression , either rings or valve seats but would need a dropdown test to be sure

Obd light on, idle rough, smell, no throttle


The obd light with tell specifically what it is, is it gas or rotten egg - the latter means catalytic converter, gas smell probably flooded or not firing on one or more cylinders, need more details. Also, if the light is flashing it's warning of catalytic damage - raw fuel hitting the cat, smell could be heat from cat trying to burn off raw fuel,it will glow red hot.

1992 Lumina Backfire - I have a 1992 Lumina Euro, 77K miles, 3.1 V-6. Under moderate to hard acceleration the engine will backfire and you can smell gas. The spark control module, coils, wires, plugs,...


I know you mentioned the EGR valve has been replaced, but you may have a bad 'new' part. I know the car is electronic, but has anyone checked its ignition timing (timing belt been looked at, I know it only has 77k on it). Is the fuel pressure regulator OK and it vacumm supply?

02 Chevy Avalanche Off idle engine runs rough then smooths out


The clamp bolt in the center of the steering column put a small cut in the #5 ignition wire and sent the code to the computer for multiple ignition failures(I forget exactly the terminology that they used and what code; I think it was 0300). The arching must have told the computer to richen up the mixture because you could smell raw fuel. I replaced the wires and ran a can of Seafoam through one of the vacuum lines(brake booster) and all seems well. If I had listened to everything I read at other websites I would have been replacing the Cats and the Ignition Coils-very expensive items. Instead it cost me $50 for a set of wires.
