#5 of 9 Re: My 99 Rodeo wont idle, hunts and stalls, code P0101 [jimsrodeo] by scott1742 Jan 31, 2009 (6:48 am)
Replying to: jimsrodeo (Jan 26, 2009 11:35 am) i don't know about the code, however i had the same issues with mine. it turned out that the intake manifold gasket was bad. it is a three piece gasket with a ceramic or bake a lite spacer in between that breaks easily causing a vacum leak. i had to order mine form the internet. make sure you order the gasket kit as there is also a gasket above this one.the gasket kit i found was from http://www.thepartsbin.com/?tpbsendcid=H1213932706W485b24a2b978b&tpbsendkwd=tpb-- bounce&om_u=$oU$Jf&om_i=_BJfsBAB7XQ5pbN& it was about 45.00 dollars and also get the injector o ring kit if you have no place in town to get one. it took me about 4 hours to replace but mine runs great now.

Replying to: scott1742 (Jan 31, 2009 6:48 am) Thanks for your reply.   I had the intake manifold gaskets replaced exactly a year ago and i was getting a code P0300 and another that indicated a lean condition on one bank at that time. That was the second time I had the intake gaskets replaced.   The code now is P0101 and P0102, MAF problems, although I replaced the MAF and it made no difference. This time I get no lean condition codes or missing cylinders. I can't believe the intake gaskets would go a third time in two years.   It appears the MAF is not able to read the volume because air is entering somewhere along the intake path. When I first start it up I get lots of black smoke from tail pipe but it disappear after a few minutes of run time. I drove it again last night and it seems to run pretty good at driving rpms and under load and is not down on power and the temperature is normal, it just won't ide and hunts in neutral under 1000 RPMs (it will hunt and fluctuate up to two thaousand when you are holding the throttle to keep it from stalling. I sure hope you are wrong about the intake gaskets as it would be the third time in less than 5000 miles they needed to be replaced. It cost me over $400. each time. If it is gaskets again then the engine's is junk or the so called reputible mechanics are morons that worked on it.   Thanks for your help I do appreciate your input.   Jim
#7 of 9 2002 Redo Transmission by losmith1 Mar 29, 2009 (2:10 am)
I have a 2002 Rodeo 4cyls that have 150000 miles runs very good , but for the past year I have been having Transmissiom problem, I have had 4 transmission repaced and all of them after 100-125 miles the trans.light come and if I push it futher it burns up. So some peploe said that the trans is overheating has anyone have this problem and how you can fix it     Lowell Replies to this message: jimsrodeo (Mar 29, 2009 5:30 am)

Replying to: losmith1 (Mar 29, 2009 2:10 am) The first thing I would check is that the trans mount(s) are correct and that the trans is aligned exactly as it was prior to when you replaced it. Misalignment with the proscribed drive shaft deflection will chew up a trans pretty quickly.   But it really sounds as though you trans oil cooler and/or lines are plugged. That will definitely cause the transmission to overheat and destroy it. I would pull the lines and check them for either bring crushed or plugged and the same for the cooler and replace it with and aftermarket cooler kit if necessary.   Jimb

Replying to: scott1742 (Jan 31, 2009 6:48 am) I finally found out what was wrong.   Faulty Idle Air Control Motor. Not only was there some carbon on the valve seat but the motor itself (it looks like a worm and sector drive that pulls the valve back and forth) needed to be lubricated with some WD-40.   I cleaned the carbon out of it first and that helped but it was still stalling, hunting and racing intermittently. I pulled it off and sprayed the WD-40 on the shaft where it enters the housing, reassembled and presto-chango! ran like a clock and has since then. The idle air control is a very precision valve so to speak and the air (and exhaust gas) has to be measured in very precise amounts or it will cause the problems that I was experiencing   The AIC costs around fifty bucks to replace but I had just dropped $165.00 on a Mass Airflow Sensor and lots of time looking for intake leaks etc.( P-0101. P-0102) and was glad to save fifty bucks by cleaning/lubricating the old one.   Jimb
