94 4runner 3vze very rough idle, stalling, running rich please help
I’m new on the forum and deeply in need of help!!! I have a 1994 Toyota 4Runner 3VZE that I blew a head gasket on. So I rebuilt the top end and here’s what I did
- Took heads to machine shop, milled and adjusted shims
-new coolant temp sensor
-new oil pressure sending unit
-cleaned out injectors at Doctor injectors (one was bad enough to cause a misfire) and new seals
-new timing belt and tensioner wp, new front end etc
-new vsv valve
-full egr delete
-Lce performance headers (open head as of now) o2 sensor right after drivers header
-all new gaskets including mls head gasket
-lce performance intake kit (retained stock maf)
-cleaned out throttle body and such
-new Bosch plugs, ngk wires, cap and rotor
-oil cooler seal
-new fan clutch
Thought it was timing and I rechecked the timing belt and everything is still lined up properly
Checked for vacuum leaks all good now (sprayed throttle body cleaner everywhere)
tried 180 out and it would just backfire and not start
very Very very little or no throttle response
would stall right away
when it does run. Will run like on the video and runs really rich
motor shakes really bad
good grounds on firewall and drivers side
and yes I tried to f+ b on diag port and still the same and even unplugged maf and still the same
NO CEL
but I am completely lost and don’t know where to continue to look
Also I could’ve mixed up the wiring to the sensors towards the back of the motor.
PLEASE HELP AND GIVE ME SOME GOOD INPUTS
