Hey Scotty, I'm a huge fan. I'm currently in need of a mechanic as honest and knowledgeable as you to take a look at my 2004 automatic Toyota Corolla CE with 179,000 miles, it's currently giving me a PO 300-304, also got po 505, and PO 171. Unfortunately, this happened when I removed the throttle body to clean it and the idle air control valve, and after replacing the gaskets and putting it back together it gave me those misfires and as of late white smoke is coming from tail pipe. I really need help, thanks you.
Well start with this white smoke is off in a blowing head gasket so do my video how to tell if your head gasket is blown Scotty. You can get one of those kits anywhere auto parts stores Amazon
Hey Scotty, it's awesome you answer. Just to clarify, I don't understand how this happened, I only took the throttle body off to clean it and as soon as I put on, the misfires started in all cylinders and the codes i mentioned started. The white smoke didn't start coming out immediately, it happened a day or two after the misfires. Before i touched the car the issue was a erratic idle and mostly low idle speed. However no issues with heating and coolant. Also how much do you think it would cause to repair if it's a head gasket. Thank you so much for your help!
Hey Scotty, turned the car on again today and the white smoked stopped coming out.
By the way the codes are 'P' for power train , and then a 4-digit number.
So it's P 'zero' xx , not P 'oh' xx. You will get better search results if you use the correct code.
