#1 of 3 2001 Isuzu Rodeo, v-6, 3.2l by dmiah298 Feb 26, 2009 (11:38 am)
I just bought my rodeo on Valentines day, and the very next day the check engine light and reduced power light came on. Since I bought it "as is", it was pointless to take it back, plus when we took it to autozone and had the codes ran it showed a misfire and we "assumed" it was a coil and maybe spark plugs also. But after changing coil #6 which was bad, and checking all of the spark plugs just to find that they are brand new- still going to change them- It still misfires. It will run fine for a while, but then when you stop at a light or stop sign the reduced power light will come back on, and you can only get speed up to 20 mph, or it will cut off all together. We figured out that if you pull over, cut it off, cut it on, then off and on again it will clear reduced power light and will drive fine again. I don't know if anyone else has this problem, but I would like some insight if you have any. Also while driving you can feel it misfiring. RPM's are really low when driving and almost at 0 when at light or stop sign.

Replying to: johnreinosa (Jun 12, 2009 5:21 am) First of all it could be one of two problems... Have the idle air control module checked and possibly replaced. These seem to go bad pretty quickly with not much warning. Will definitely cause more issues if not fixed. Secondly... Have the transmission checked out. If you go to AAMCO they will do a free diagnostic internal and external trans check. It turned out that mine had a SERVO GASKET COVER leak. This is not an expensive part. Do not let AAMCO put the part on for you either. They tried to charge me $800 for parts and labor. Call Isuzu- part plus labor = $200. If you call around with that quote, more than likely you will find a shop that is gonna match the price. Good luck.
