1997 2.7L 4Runner
OK, I tried the Seafoam thing. Slowly added it to the intake PCV hose.
Followed instructions.
(Truck ran/idled fine before Seafoam. This was just for PM).
After Seafoam, the idle wasn't as smooth as before.
New plugs didn't help.
I cleaned the TB and IAC valve. No difference.
Checked and tested EGR. No difference.
MAF cleaned.
I have no CEL or codes.
No vacuum leaks.
The idle quality isn't terrible but wasn't as smooth as before.
The only thing I haven't done is physically cleaned the O2 sensors.
I figured that if these were bad, I'd get a code
Anyone with the same neg. experience with Seafoam?
I wish this 4Runner would Idle like my 96 Cruiser......
