Hello,
I am having some issues with misfires specifically cylinder 6. I have read several postings on hear about this topic and tried almost everything mentioned. Looking for some advice on what should be next. 4Runner has 315K on it and timing belt, water pump, plugs, wires were all done then at 288K. I haven't been driving it really at all the past few months when this started since I have a Tundra to drive. This is what I have done since the issue came up....
1. Replaced coil for cylinder 6 & 1
2. Replaced plug wires
3. Cleaned MAF and throttle body
4. Swapped plugs from 4 & 6.
5. Checked cylinder compression and all were in spec and within 10psi of each other.
6. Cleaned air filter
7. Added seafoam to tank. (Have driven it through most of the tank)
Codes showing yesterday prior to cleaning MAF again. Now just cylinder 6 misfire shows.
Plug that was in cylinder 6 before I swapped them around. Others look about the same
Suggestions on what could be the issue? I am thinking injector but have heard they rarely go bad.
