My buddy bought an 88 gl wagon with the ea82. A few days ago he was driving around running errands and the car just all of the sudden started acting like it was choking itself out. It runs great at idle, but it won't rev past 3 grand unless you go super slow. The fuel filter is new and we just put new plugs wires and a rotor in it today and its still acting weird. What do you guys think it could be? We also ran some seafoam in the gas.

Do you guys think a bad tps or iac could cause this to happen?

probably timing belts.

 

well, the one on the passenger side likely is snapped.

Are you sure? The car runs great at idle.

Badly plugged exhaust or weak fuel pump,perhaps.

Try running w/the MAF unplugged too.

Any codes?

Well its not the exhaust, my buddy hacked it off as soon as the problem started. That was one of the things I fixed yesterday. We got a cherry bomb, an exhaust adapter, and a couple of clamps. Only problem with that though is the muffler is sitting tight against the carrier bearing.

I think the fuel pump is ok, I put a clear filter in under the hood and when the car is running the filter stays full. That's at idle and when we're trying to get it to run over 3xxx rpms.

The car just dies when you unplug the maf. I have some maf cleaner at home though, I might spray it down with that stuff couldnt hurt.

No codes either.

make sure the green test connectors are not plugged in, as this will hold the timing static and there will be no advance curve.

Is it like my dads 91 and they're under the steering wheel? Or are they under the hood? I remember him saying something about unplugged wires under the hood, but I don't know if he plugged any together.
