Customer Question
I have a 1999...

I have a 1999 Toyota Tacoma 3.4 l engine once the engine gets warm if I try to restart it it runs like it's only running on 4 cylinders and it's only happens after it gets warm please help

Mechanic's Assistant: How many miles are on the car? Is it an automatic or a manual transmission?

It has 405,000 miles and it's automatic

Mechanic's Assistant: Are you fixing your Tacoma yourself? What have you tried so far?

I replace the spark plugs to spark plug wires all three coils

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Not that I can think of at the moment
