The 88 22RE is giving me a hard time currently. When I rev it up it dead misses at 3500RPM and will not go above. going down the road in 4th and 5th gears if I start to pull a hill around 2500 RPM (45 MPH 4th, 60 MPH 5th) it will misfire. I've changed the Distributor Cap, Rotor Button, Plugs, Wires, and fuel filter. Normal thinking would say the Vaccum Advance has gone bad but there is no vaccum advance on the distributor which leads me to believe it may be in the EGR system. I'm jsut curious if anyone else had a similar issue and knew of a possible culprit. I know the Vaccum system leaks like a sive and I'm waiting for the FSM to finish d/l'ing so I can get a good diagram to re plumb it by (the under hood one is too faded to read).

Is this a new problem or did it happen after some of your fixes? And yes I would definitely get those vacuum leaks fixed first.

Huddleston eh? Well...you're just down the road.

double/triple check your timing first.
make sure that when you insert the jumper in the diagnostic port Te1 and E1 terminals the idle speed noticibly changes. if it doesn't go to TPS check and adjustment.

otherwise, any trouble codes?

had that problem with my 77, and it turned out to be the fuel pump.

Check the ground from the AFM. You can try grounding the AFM directly. If this solves your problem, you have a bad ground in the ECU and it's time for a new one...

Timing was off a little bit, checked, cleaned, and adjusted the TPS. Still doing it. gonna go for the fuel pump this weekend (I was gonna do it anyway)

Trouble Codes: 51

What is the AFM?

If it seems like im not too worried about it its cuz I have an S10 in pieces right now re doing the tranny and its kicking my ---

AFM is Air/Fuel managment or something if im not mistaken?

Found it finally. the Cat or muffler was clogged. didnt check to see which it was but I replaced the muffler and took care of the cat, I'll order a new one next week from Jegs really pleased with the one I put on the S-10 (that and they are cheap)
