Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I can help you. I have been in this business since 1975 and also teach automotive repair. I am confidentwe can resolve your problem together. Please understand that I don't know your skilllevel. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies toget to satisfactory results. Please be patient! I also try to give all of the information you may need, expecting a “positive rating” inreturn. I will also continue assisting you after you have rated me, if necessary. If thereis any reason I cannot get a positive rating, please let me know why “in advance”, so Ican go another direction for you. I am sorry you’re having this problem; I’ll help youthrough it.I think at this point, it would be best to do some testing with a scan tool and a lab scope. ALL those parts must have been expensive. Start doing your tests with codes first, then check wiring to the coolant temp sensor and check for a heavy carbon buildup in the intake.
I already told you what needs to be done, are you willing to perform these actions?
