95 wrangler idle question

is their anyway to more the idle up a little bit on my 95 wrangler with fuel injection? it seems to idle to low and it starts to shake anyway to fix it, it idles as low as 400rpms and it really starts feelin bad.
thanks!

Re: 95 wrangler idle question

First, clean the throttle body, they gum up with deposits from the crankcase breather. If that doesn't fix it, have the idle stepper-motor checked, they sometimes seize and won't allow the computer to adjust the idle. A new one costs around $65. The engine should be able to maintain 750 rpm /- 25. There was a TSB on earlier 2.5s (possibly 92 or 93) where we installed a jumper across 2 wires in the A/C connector to trick the PCM into thinking that the A/C was on, this gave an idle of 850rpm and smoothed things out some. The TSB gives a part# for a special jumper/plug to replace the protective cover on the A/C prep connector. The connector is a black six wire oval plug, above the firewall junction block, near the support rod to firewall bracket. Remove the protective cap, (you probably don't have A/C) and you will see 5 terminals in there. There are 2 blue/light blue wires diagonally across from each other in the connector, a small wire jumpered across them will tell the PCM that the A/C is on, boosting the idle rpm goal. The jumper needn't be much larger than a staple. Replace the cap and you're done. Hope this helps, good luck!
