zj idle issue
my 98 zj has an issue during idle where it will idle up and down.....between approx. 600rpms to about 1200 or so(maybe 1100). recent dist cap, rotor, plugs, and wire change. airfilter looks good as well so im thinking its a fuel problem.....either fuel pump/filter, idle air control valve, or even injectors. wanted to know if this is a common issue and if anyone else has had a similar problem and what it was.

Is there anyway to check to see if one of those is bad without taking it in? I doesnt always do it. I need to pay more attention to when I does. I know it does it more after you first start it.....I also believe when its cold out it gets worse

My 97 ZJ was doing this over the summer. I tossed a new TPS in it and it fixed the issue. Here's a link to the 4.0 ones that we carry if that's even the issue.
