Here how to check to see if it is working (mechanical valves only) Have the vehical running take your hand under the egr valve and push up on the plunger if the car stumbles your good to go if not new valve or check for kinks in vaccum hose

The good news is they are easy to change. Fel-Pro makes one that is softer, with steel inserts to keep it from getting crushed. You should be able to change both sides in less than two hours.

Replying to: inkaddiction (Oct 29, 2009 5:58 pm) There is a 3 wire pigtail located on the hump on the driver side just where the console meets the carpet and is usually tucked under the carpet. Just follow the carpet end til you meet the console and it should be in there. You jumper the right two wires and turn on the ignition key and the CEL will flash the codes it has stored, one after the other if there are multiple, and repeat a couple more times IIRC.

Hi,   I am new to this forum and found this very helpful..... I have one question though.. I have 2002 Trooper which runs perfectly fine, but from last month and a half I noticed that CHECK light is keep coming up, its right under TOD sign, its not the constant but keep coming now and then. sometime when I start engine it stay there and flashing then I turned-off and turned back on then it goes away.   Any idea what is it for, I will really appreciate your help.

Replying to: biryani (Nov 21, 2009 1:32 pm) When the Check light comes on, there is also a code stored in the computer, which can be read by a OBDll code reader. Autozone and most part stores will read it for free. Get the name AND the code number and that will give you specific reason for light. Then you can research possible remedies. Hope this helps. One guys opinion.
