    Hello Merlin,
    I have a question I hope you can answer for me.
    I was filling the fuel tank on my 2004 Silverado 2500 HD while the engine was running, now it is kicking a evap code P0449 Evap circuit out of spec, or something like that.
    There was no code before filling the tank, I replaced the gas cap with a real Delco cap and cleared the code but it has returned. Can you point me in the right direction? I have skills and the tools just not the knowledge of this system.

    Didn't get any reply when I made a post on the message board.If anyone can help I know its you. My 99 escalade has been at the dealership for a couple of weeks I purchased with bad enigine I installed a engine fom a 99 1500 PU. It had a bad miss it which I determined to be a bad injector. I replaced the spider set but now its running rich. It will run smooth for a couple of minutes then begin to flood. I have replaced the o2 sensors as well as the exhaust system. Also have a new fuel pump(holding good pressure) timing is at 1 degree. new crankshaft,camshaft sensor,throttle positon sensor. plugs /wrires. compression is good. Cats are burning super hot. muffler cherry red. Computer is showing the voltage on the o2 sensors when it starts running rich going from the normal .5mv to over 1000 mv. I am stumped as resorted to dealership that apparently knows no more than I do. Could this be a ecu issue or new prgm to the vehicle it was pulled from? running out of ideas here.

    My wifes 2003 Chevy Trailblazer LTZ that has 96,000 miles on it and it bogs out and stalls at a stop, sometimes while trying to press on the gas pedal to go. After it stalls, I get a message saying that "oil pressure low". I just really need to get this fixed a.s.a.p. She drives around with our 9 month old daughter in the truck and I bought this for their safety. Please help me? I was reading some blogs about the CAM POSITION ACTUATOR SOLENOID? If I change this, will my problem stop? Please let me know if anyone can help me. There is also a CAM ACTUATOR SENSOR. Which do I replace? How do I solve this problem? We just had a 100,000 mile service & tuneup done as well.
