#7 of 44 2002 Rodeo by shjhhudson Feb 17, 2008 (7:01 pm)
got an initial idling problem. 6 cyl 2002 Rodeo. When cold, it won't stay running until I restart 4 or 5 times. Check engine light is on.. faults that showed were EGR and O2 sensor. Runs fine when warm. Any ideas? I don't want to just start replacing parts I don't need.

Replying to: hagasn (Dec 31, 2007 3:32 pm) i cant remember if its throttle body fuel injection,so if it is you might want to check the iac[idle air contol] might be dirty with carbon,or need replaced hope this helps.ihis is for the 91.the newer ones with multiport will have the iac also but will give a code for it
#9 of 44 1992 trooper (sohd) by daukstrooper Feb 19, 2008 (10:59 am)
I just bought myself a new toy a 1992 trooper. it had some problems but it was so low on miles i had to take it. 112k miles. I changed the plugs, oil air filter, most of the vaccume lines, fuel filter, checked most sensors the seem to work, ran sea foam through out entire vaccume line system and break booster line, I think the IAC VALVE could be bad. The problem is when I want it to start I have to really be on the peddle in order for it to start. once started it runs rich a little bit of smoke and then has a fluxuation in the idle between 800rpm-1200 rpm's. ANY HELP PLEASE thank you

Replying to: inspector32 (Feb 16, 2008 10:59 am) ok ive changed plugs,plug wires and plugs are only 6 months old.Changing the plugs got the rodeo to where itd crank but its doing as it did before it died,it will bog down and barely go,then check engine light comes on and it runs great,im thinking its cutting something off by default,then when it comes back on it starts messing up again.Does anyone know if im on the right track in thinking its fuel pressure regulator problems?ill change oil next cause i do have the fuel smell in the oil,hence the black smoke from exhaust

#13 of 44 Adjusting the MAP SENSOR by mrmouse3 Jun 10, 2008 (10:14 pm)
I have a 95 GMC pick-up with a 305 engine. I just now put in a modification to run my truck on HYDROGEN (water). How can I adjust the MAP SENSOR so I am getting less gas. The HYDROGEN combined with the gas almost double the octane so I now need less gas to the engine. Is there a MAP SENSOR that you can adjust? I need to fool the computer so I can tell it that the engine is running to rich. Replies to this message: tidester (Jun 11, 2008 5:50 am)

#16 of 44 WON'T CRANK by yellowgw Dec 19, 2008 (7:51 pm)
I just towed a friends 95 Rodeo to my house. This is what he told me. He was driving down the highway and all of the sudden he started to lose power. He would press the accelerator but nothing happened. He finally coasted to a stop and then the vehicle died. He was unable to get it to start after that. 1. I have tried jump starting - that did not work 2. All lights - both interior and exterior work w/out having to be connected to jumper cables 3. The vehilce was completely out of oil when I checked. Took 4 quarts to almost fill 4. I don't think it is the battery or alternator. 5. The only thing I can think of is:      a. The starter is bad      b. He drove the thing dry for too long and locked up the engine.   Any suggestions? Agree or disagree?   Vehicle has leaked a lot of oil since I got it home two nights ago.   Thanks,   DJ Replies to this message: tidester (Dec 19, 2008 9:38 pm) yellowgw (Dec 19, 2008 9:43 pm) tidester (Dec 20, 2008 12:46 pm)
