Need the collective minds and wisdom of mud nation
Couple of disclaimers. I am a rookie mechanic. I have spent hours researching on line forums and am a rated pest on the Howell hot line. To say I have asked too many questions is an understatement.
The system was put on about 10 years ago on my 75 FJ 40 2F. I believe by Sam’s off road in Cali. Did it. When I bought the vehicle 3 years ago it ran ok but eventually it started to start and run rough, including sputtering, bogging no power and intermittent stalling. Here is what I have tried so far:
-adjust FP to spec 11-13
-adjust timing, tried several settings
- has dui distributor
-checked for vacuum leaks. Replaced some lines anyway
- moved map sensor vacuum to back of TB and above TB. It runs better w map in front of TB, head scratcher.
-replaced map sensor and ecm as a result of pulling codes 33&34
- replaced fuel filter
- removed gas cap as I read this can helo venting?
Through each phase of these updates there has not been much improvement .
Needless to say I’m frustrated as it shouldn’t be this difficult, should it?
Any help would be greatly appreciated or should I just replace it with a holly sniper LOL
