Hi there: So I just bought this 1993 FJZ80 a few weeks ago I brought the truck 50 miles away from home without an issue, park it for a few weeks and the day I took it to pass the emission test it died on the smog test station...brought her home after it cools down (15 to 20min).
Cold start is good
CEL is present when key on
No CEL light when running.
Idle gets rough after reaching normal operation temp
Acceleration when its warm feels retorted
strong gas odor
If I turn it off it will crank but won't start again
I let the truck get warm and fail to test it today and there's spark
I also check the EGR applying vacuum to the hose on the drivers side and there's resistance but in the other end where the hose is connected on the intake manifold I found that was totally clogged with rust
That means that the EGR is not working right? so isn't the CEL suppose to light on for a code?
Anyways I cleaned it with a tiny wire I also cleaned the EGR actuator and tried again ...start it cold let it warm again but no luck it fail again ...what else do I need to check ?
Thank you in advance you guys
