1986 4runner 22re. Used for off road only.
In June what ended up being a broken fuel injector plug led me down the road to replace the following before I found it:
-Intake boot
-EGR Delete (to simplify troubleshooting)
-fuel injectors
-TPS (from LCE and calibrated per 4crawler)
-coil pack
-fuel filter
-all new vacuum lines
Ran great for a 4 days weekend outing and ran great when parked. Go out a few weeks after and start it up and it still ran great. Have a trip next weekend so I figured with 2 weeks to spare I should take care of the oil pan leak.
So I pulled the oil pan and found peices of a timing chain. Pulled the valve cover to inspect the chain and it's all there. Must have been part of a previous repair I figure. Get it all back together and it runs like total crap. So I start racking my brain
--20psi vacuum
-replaced PVC and grommet
-40psi fuel pressure
-pulled each plug wire 1 by 1 and each one evenly wanted to kill the motor
-with jumpered timing is +5 degrees
-no CEL
-all grounds are connected
Will idle with the diagnostic port jumpered but won't rev, without the port jumped it'll start and stumble and die. Sometimes it'll go longer than others.
Everything is basically new, and I didn't touch crap when I did my repair. I'm in day 3 of scratching my head and reading
