  1. Cps got it! Got the trash out of the transmission bell house etc. we ran 6 hours last night problem free as far as motor is concerned minus I need to increase fuel presssure back up. You can tell it is fuel starving.  That said my 5th gear started popping out a few times then it appears I have lost it all together now so here we go again. Appears to go in gear but there is nothing there it seems. Gonna check cable adjustment and if that doesn’t get it then guess I’ll have to pull the bugger out 

  2. I think I found it! Completely pulled entire fuel system again tonight and recleaned and rewired pump to a toggle for testing.. no dice. For Shits and giggles I dumped pressure at 100psi and it reved up mostly normal sounded then I heard it retard then drop timing.. while this is all happening I hear that random familiar sound of what I thought may had been detonation then a pop. A bb size hole next to my crank angle sensor appeared. Pulled crank angle sensor out abs the entire damn sensor is completely eaten away. They said it ran great until clutch job.. now I believe it lol.  So can I get away with just pulling the tranny apart from housing bolted to engine or do I have to pull the entire damn thing off the motor? I am Just assuming there is no access hole so I can get the remainder of the crank angle sensor out of there without pulling it apart? Makes sense those because my tachometer has been appearing super sluggish and sporadic.

  3. Joyner usa told me they feel it’s fuel. Not sure what else to try as far as fuel is concerned. Filter, pump, fpr and lines all replaced. Tank cleaned and verified via clear filter that it is keeping solid fuel supply. I was running 50psi, they said 60+ recommended so I will try that tonight. Did get a map sensor on the way and a new tps. My current tps when checking resistance was ranging from 2 at close to 7 at open. I believe I had read it was suppose to be no more than 2 at open.

    I don't think the firing order is a problem.  If it were, the engine would run poorly at any RPM because it would be as a result of changing the plug wires on two of the cylinders.  You'd lose 50% of the power.  A 4-cyl engine fires every 180deg.  If you swap two plug wires, then those two cylinders would fire either at the top of an exhaust stroke and/or bottom of the intake or power stroke depending upon which two cylinders were swapped.  Backfiring through the intake could be one symptom.  The standard firing order on most, but not all 4-cyl engines is 1-3-4-2.

    How is the Mass Air Flow Sensor?  Is it clean. A bad MAF can cause drivability problems.  It tells the computer how much air is going through the engine.  If, at 3k RPM the MAF is saying less air is being moved than actual, the computer will not allow as much fuel as needed at that RPM.  There is a cleaner for it.  Just remembe while cleaning it, do not touch the really fine wire in the sensor.  The only thing that should touch it is the cleaner - no rags, no Q-tip, no nothing else.

    Were you able to test drive it before you bought it?  Did it run good then?  If not, then I don't believe it ran good per the seller's statement.

    No I wasn’t able to drive it. It had a bad shaft seal on tranny from a botched clutch job.  I have not cleaned maf,  will get some cleaner today. Also see if I can find some o2 sensors that will fit since I can’t find part numbers anywhere 

  5. I aM so f%{%{%{%ing frustrated. Replaced fuel pump, fpr and all lines just to verify it cannot be fuel system. Checked the injectors for flow and they are spraying well. I got 50psi until 3k Rpm when it cuts spark.. still fuel pressure isn’t moving. It’s like hitting rev limit or it dropping cylinders etc. is there any other forums to check? I’ve read through this and I see people talking about limp home mode from sensors but I don’t see how to test said sensors. I don’t want to waste 700$ abs 3 months waiting on them from China.

  6. Replaced the fuel filter. Got a new pump on the way as I have no way to see if it’s dropping pressure when I’m driving it. At idle when I first start it, it revs out fine. After a minute I want to say it breaks up. Basically it gets to 3k and completely stops reving and sounds like it’s dying and bucks. This is in any gear. I did start motor and start disconnecting sensors and I noticed running difference when unplugged on almost all of the engine sensors.  I wish there was a way to test these sensors since we have no way to get codes. Feel like I’m just throwing money at it until it runs.

  7. Hey guys just bought a 07 trooper. Previous owner stated it ran great etc prior to clutch job then had issues. I drained tank, replaced plugs etc. found one of the injectors connectors was not connected and plugged it in. Solid 50psi fuel pressure.  It starts easier than previously on 3 cylinders but still runs very very poorly. I’m thinking the sound I’m hearing is it detonating at around 3k. It kinda sputters and falls apart. Sounds like clicking or something when it happens. I am at a bit of a loss, compression is a solid 150psi across the board with no movement. Verified spark and now am assuming all injector are functioning more or less correct as if I unplug any one it sound terrible at idle. 
     

    A note, I tapped plugs at .7 manual called for .9-1.1 but that seems super over doing it but I will try adjusting them to 1.0

    additionally I’ve noticed the fan in rear doesn’t turn on. 
     

    anyone with any help I will be in your debt.
