#2 of 9 rodeo - help w/ opening back trunk and window by marysoden Dec 27, 2008 (11:23 am)
cant find a consistent way to open the trunk. lock seems to unlock, but window won't open. does the window have to open first, then the door??? does the key have to be held in, and why does it work sometimes and not others????
#3 of 9 My 99 Rodeo wont idle, hunts and stalls, code P0101 by jimsrodeo Jan 26, 2009 (11:35 am)
This problem started out intermittent with the first code P0102 Mass or Volume circuit, low input. As the problem became more frequent the code became P0101, Mass or circuit range performance problem and then it was no longer intermittent but refused to idle without foot on accelerator pedal, would hunt and stall.   I replaced the Mass Airflow Sensor and aircleaner element. Checked the connector and cable to the loom for bad connections, (visual for brecks etc.) could find no obvious problems. Unplugging MAF sensor makes no difference in helping poor performance.   Did notice something odd when engine is shut down a destinctive hissing is heard between the back of the engine and the firewall. It does not sound like intake leak as the noise is high on the firewall like its coming from one of the solenoids or vacuum lines on the upper plenum and only after you shut the engine off.   I do not believe it is intake gaskets (again) as I have had them replaced twice a year apart just a year ago. The code for the intake leak was P0300 and another that indicated a lean condition on one bank of cylinders.   It does not sound like the MAF signal is getting to the PCM or the ECM. Does the 3.2 V6 Rodeo have a MAF relay?   If any body has any ideas I sure could use some help. My diagnostic equipment consists of digital multimeters and other assorted continuity testers. Nothing exotic like laptop diagnostics. Thanks Replies to this message: scott1742 (Jan 31, 2009 6:48 am) jimsrodeo (Jan 31, 2009 9:44 am) jimsrodeo (Mar 29, 2009 5:45 am)
#4 of 9 98 Isuzu Rodeo brake issues by bkh811 Jan 26, 2009 (2:08 pm)
Two days ago I was driving and when I went to apply the brakes the pedal went all the way to the floor with no resistance before barely catching at the bottom. If you pump the pedal it will give you full pedal like it should, but after driving for a short distance it will do the same. I have good brakes on the front and new on the back. I bled the line and the fluid came out but not with the force it should have. Any suggestions about possible causes before I give my money to a garage?

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
