Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
Well..... sort of.....
You have to pull it off perfectly square with the backing plate on the
TB or one side of the clip will usually snap off. Old spring steel and
the slightest corrosion..... When you snap this clip, you can do a
decent paper clip bracket to hold it back on or you need to buy new
linkage... My 86 CJ7 has the paper clip fix thanks to Bill H.
I will go look at the 88's to make sure it is the same.
OK, nope, it is a plastic clip on our 88 with maybe a spring clip in the
end of it. It 'looks' like it should pull off square, but I don't know
for sure...

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
Well..... sort of.....
You have to pull it off perfectly square with the backing plate on the
TB or one side of the clip will usually snap off. Old spring steel and
the slightest corrosion..... When you snap this clip, you can do a
decent paper clip bracket to hold it back on or you need to buy new
linkage... My 86 CJ7 has the paper clip fix thanks to Bill H.
I will go look at the 88's to make sure it is the same.
OK, nope, it is a plastic clip on our 88 with maybe a spring clip in the
end of it. It 'looks' like it should pull off square, but I don't know
for sure...

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
So I did my thorough cleaning of the throttle body, and it seems to run
smoother and more consistent. Don't know about eating off it, but there's
no more black gunk in there. But now immediately after firing it up, it
goes up to about 2000 rpm, and sits there.
I tried unplugging the two sensors (one at a time) and then starting it up.
When I did that to the IAS, it started like I had my foot on the gas (rapid
increase in engine speed). Shut it down, plug in the IAS, then unplug the
TPS. Well, that made it run exactly as it did with it plugged in; start and
run at 2000 rpm. So I'm thinking the TPS is shot, and I should replace it.
Make sense? I had tried adjusting the TPS with no joy as well, even when I
went to one extreme to the other. I haven't re-measured the output of the
TPS; I'll probably do that later today. But it seems it should be doing
something useful.

smoother and more consistent. Don't know about eating off it, but there's
no more black gunk in there. But now immediately after firing it up, it
goes up to about 2000 rpm, and sits there.
I tried unplugging the two sensors (one at a time) and then starting it up.
When I did that to the IAS, it started like I had my foot on the gas (rapid
increase in engine speed). Shut it down, plug in the IAS, then unplug the
TPS. Well, that made it run exactly as it did with it plugged in; start and
run at 2000 rpm. So I'm thinking the TPS is shot, and I should replace it.
Make sense? I had tried adjusting the TPS with no joy as well, even when I
went to one extreme to the other. I haven't re-measured the output of the
TPS; I'll probably do that later today. But it seems it should be doing
something useful.
