NA Misfire Problem

[Neil]

I hate to gunk up your guys's forum with na stuff your just faster at the respond time.
My ge officially got 191k on it and now i'm finally seeing some problem. It has an intermittant misfire problem and I can't really figure out the conditions for it to happen. It starts to sputter and spit on acceleration of course with the jerky motion to follow. Starts and runs great most of the time but this is the second time it's happened within a month span. I did notice that it idle's rather high while it's doin' this misfire problem. I've read and also assumed: ISC, and TPS. I'm sure there are other possabilities so I'd like to hear them all and maybe a nice way to test them including the isc and tps please.... I just hope it's not a sticky valve.

I don't see were you tried to post this in the NA section?

With 191k I would start with a basic tune-up. Plugs, wires, cap, rotor. Maybe get your injectors cleaned and tested.

You can check the TPS with a ohm meter.

Like I said you guys reply faster and I'm not gonna argue further than that.

I actually did a full tune up minus injector cleaning in may new plug wires and all that. It was all done right. So that almost takes that out of the question but I will definately check into it.
