    2001 Corolla - Misfiring and Running Too Lean

    Older cars had a smaller gap. Newer cars have stretched that gap by increasing output voltage of the ignition coil which creates a stronger spark. Independent AMSOIL Dealer, Contact me to get the world's best oil for prices lower than brands like Mobil1 and Royal Purple...

    2001 Corolla - Clinder Misfire, Catalyst System Failure, ECAP

    2001 Corolla - Clinder Misfire, Catalyst System Failure, ECAP

    You'd be checking voltage at the coil packs. Remove that connector from the coil packs and check for voltage on pins inside the connector (the one hooked up to the wires, not the connector on the coil itself). Independent AMSOIL Dealer, Contact me to get the world's best oil for prices lower...

    2001 Corolla - Clinder Misfire, Catalyst System Failure, ECAP

    You could do that. It would kill a cylinder. If your idle does not change then that cylinder was dead all along. I wouldn't do it because I don't like getting shocked by tens of thousands of volts. Independent AMSOIL Dealer, Contact me to get the world's best oil for prices lower than brands...

    2001 Corolla - Clinder Misfire, Catalyst System Failure, ECAP

    Nevermind, I see what you're saying. Could you? Sure. Ideally it would kill one cylinder. Would I? No. Ever been shocked by 50,000+ volts? I have and I don't want to do it again. I would swap the coils and see if your misfire moves. On your vehicle all coils are the same so its not an issue...

    Reprogramming ECU

    You can get a programmer that will change the timing in the engine to burn a higher octane fuel at a more effective rate. Essentially this means more power. You will lose fuel economy. Unless you change the ignition timing (through the use of an external tuner or reprogramming your ECM)...

    2009 - Should I Change the Oil?

    Many people use that method for the exact reasons you listed. Whether it is laziness, physical impairments, or a damaged plug. However, I always recommend using the drain plug. There is a reason manufacturers install a drain plug. Independent AMSOIL Dealer, Contact me to get the world's best...

    2009 - Should I Change the Oil?

    As far as the oil caps go, on some engines it is more noticable. Breaking the seal on the cap does allow the air pressure to push on the oil more efficently than keeping it sealed. However, on some engines it is almost not noticable. On my 94 jeep grand cherokee 5.2L v8, you couldn't tell the...

    2009 - Should I Change the Oil?

    Changing the oil in that method is not as good for the engine. When you drain it from the bottom, almost everything comes out. The oil on top forces the particles on the bottom of the pan out of the engine. When you suck it out you tend to leave more particulates in the pan. Independent AMSOIL...

    You've Got To Be Kidding Me...

    I bet you can literally see smoke rising off of me right now. This is ludicrous. I owe $30,000+interest to the government in student loans for my education. I worked and went to school the whole time I was there for a total of about 70 hours a week. I finished as one of the top in the nation...
