High speed misfire

  

0
Topic starter

It happens at higher speeds like when I'm driving at like 80, 90 mph and when I set the cruise that's when it happens. I got new spark plugs, new coils, new gasket, new solenoids and also the filters for it but still it's happening. It's a 2006 Toyota Avalon limited edition with about 207,000 mi. I have not scanned the vehicle but it's usually two and four. Those are the ones are misfiring. I even use the Barney's cleaner for the fuel tank. I have got the furnace cleaner for the oil change but I still haven't done that. I'll do that on the next oil change or so. But I want to send my vehicle to you and you can check it out or I can bring it to you if you want. Please let me know. Thank you.

Safety considerations aside, that may not be the best thing for a 20-year-old, high mileage car.

Were those parts actually bad (did you check them before replacement)? What diagnostic steps have you taken so far?

I have not scanned the vehicle

That is a necessary first step when troubleshooting a problem.

What is "Barney's cleaner" and what were you expecting it to do? (Is it the 505CRF product that Scotty sometimes talks about?)

Furnace cleaner???

See the FAQ for information on contacting Scotty to make an appointment.
