Question about 2000 Toyota Tundra
Engine was changed due to existing one ran low on oil pulling a trailer. after engine change, truck ran great for 1.5 weeks, then the engine misfires started occuring. At first they changed the used igntion coils around. Then a bad connection at the computer issue. Then another misfire on #7, installed a new on, then #8 misfires, then had all of them changed to new. Trouble free lasted 4 days and now, 2 days in a row of misfires.
Change the spark plug wires.

Testimonial: "I will let you know. The Tundra is 2 hr drive away, will drive to get it, switch rigs and hopefully drive it back to a dealership close to where I work. Dealership hopes that the truck comes back and misfires for them besides checking for the computer code."

Did u find code p0306 comes up ? Two things can cause this if the plug and coil have been replaced.the intake manifold may be leaking in the area of cyllinder 6 or its a mechanical issue.try doing a cyllinder misfire test and also check the compression on all cyllinders

my name is Jerry Tiet. Base on my experience on 1998 Toyota Sienna with the DTC P0303 show there is a misfire in cylinder #3. a possible cause is the ignition coil of the #3 cylinder. Compare the resistance value of the ignition coil of cylinder #3 with the other coil or simply switch ignition coil #3 with one of the other ignition coil and clear the DTC with the scan tool. Then run engine for couple days. If the check engine light on again. Let me know what is the DTC code.
