  1. 1987 2wd automatic transmission in SLC for sale

    I have an automatic transmission out of a 1987 2wd cargo van for sale. The engine was toast when I got the van, but the previous owner said it shifted fine, didn't clunk, didn't slip. The fluid looks...

    Re: How to pass CA smog????

    I know you've covered some of these, I'm just listing everything I can think of.

    Idle pop, and random high idle HC:

    Cap, rotor, wires, timing
    Vacuum leak
    Computer doesn't know it's idling,...

    Re: How to pass CA smog????

    Yeah, fix the EGR system. Sounds like it isn't functioning. I like seafoam, works great. Replacing the O2 won't hurt, but if your HC, and CO are good I would guess it's not needed (replacing them...

    If your HC and CO are good at both 15 and 25 then it would seem the engine is running efficient.

    NOx emissions are effected by increased cylinder temperatures. Exhaust gas recirculation (EGR)...

    I don't think you're crazy. I have about $10k in engine, turbo and overlanding gear on one of mine, and yet you can put your finger through most of the body panels. Wait, maybe we're both crazy?

  20. Re: Van started running rough? Misfiring on clyinder 3?

    The resistors are there to ohms match the low impedance injectors to the ECU injector drivers.

    If a resistor is bad it usually creates an open circuit and the corresponding injector won't open.

    In general higher oil pressure is better. When warm, off idle, It should be toward the top 3/4 mark on the gauge, in-between the two marks that delineate the acceptable range.
