Anyone ever had problems with the car stalling after putting 87 gas? I loan the car to a friend and he ended up putting 87 in it and now she either turns off right after idle, or will turn but won't crank. I have to leave it alone for about 10 minutes so it can crank. It also shuts off if I'm in idle (stopped) for too long. Could this be a gas problem or something else? I also thought it could be the alarm kill switch put switched it to valet (clifford 770 with all the extras) and it does the same. Anyone out there ever had this problem? The car has a few mods and is used to running on 93. Thanks in advance

 

You must have some major mods for your car to have withdrawls from high-octane fuel. I've never experienced this, but cipher the 87 octane out and try 93, or just use an octane booster. Hope this helps.

 

I've thought about adding an Octane booster but wasn't sure what if it might effect the car. I have minor mods, cams, pulleys, plenum spacer, headers, test pipes, exhuast, ecu reflash, msd ignition, flywheel, clutch and intake. All N/A I've ran the car with 93 since day one and occasionally let it run empty and add 110 (usually only add about 1/4 to 1/2 a tank of gas to keep it light). Could the injectors be going bad or something?

 

I added the octane booster and more fuel. It's dieing down so that might be the cuase. I'm still taking it in to my mechanic to have a look at it and see what could be the problem. You guys think it could be a O2 sensor?

Any help guys?

 

I took it to the mechanic and he said it had nothing to do with the gas added. He said it's my Cam sensor and my 02 sensor (from the diagnosis/hooked up the computer to it). Any one know where I can get these parts cheap? I've called around and the cheapest I've gotten is $48 for the cam sensor and 93 for the 02 sensor. Anyone know of any place for cheaper parts or is that a good deal?
