#1103 of 1448 Re: Running Lean....Check engine light is on 
Mar 10, 2007 (3:25 pm)
I had this *exact* same sounding problem on my 2000 Prizm -- it also cost me some serious cash before figuring out what the problem was. Check the Mass Airflow Sensor -- mine was running a little lazy and chaotic. I ultimately had to take to the Toyota dealer before they figured out what was wrong. Apparently it was a fairly common problem on the Prizm/Corolla models of that time, but the Chevy guys didn't know jack about it and were just recommending replacing parts.
I have the Chevy manual for the 2000 prizm and ran through the various diagnostic tests myself, but was never able to come to a conclusion. While at the Toyota shop, I looked at the corresponding Toyota manual for the 2000 Corolla and it was much more insightful. It gave a specific test for determining if the MAF was functioning at appropriate values.

Thanks for the info. I will check it out and see what I can come up with. It also has some exast noise coming from under the hood when excelerating. I think that is the exast oxygen sensor. Thanks again.

I am helping a friend out with her 2002 Chevy Prizm. She lost the owners manual, and we are trying to figure out how to change the time on the radio.

Just bought my first car, 93 geo prizm and am loving it, its a LSi, 85K miles bought it for 2000. manual with alloy wheels, does have a few lil things here and there but overall im loving it especially witht he corolla engine, nice reving engine, decent power, looks nice, classy interior for its time, handling is amazing for what it is, took a few turns at 90, loooong sweeping turns and it stuck to the road. did the top speed at 115 till fuel cut off, got threr pretty quick. some problems with it, driver side mirror is a little loose and almost comes off, need to tighten the screws, drum brakes are rusted, need to do something about that, also has ABS equipped

#1108 of 1448 weird starting probs 2
Mar 24, 2007 (6:35 am)
my in law has a 91 prism and is having weird starting problems 2. it decides when to start and when not to. have had batt. cable replaced and new starter after another put in. Has had new alt and belts and still will only start every now and again. has had new ignition put in to but always does the same thing. The mechanics are as dumbfounded as we are. They keep replacing and the car still acts as it has a mind of its own. We tryed to start it the other day and it wouldnt start. Went to try again in 10 mins and it started without any trouble. Took it to resturraunt in town just a few miles away and wouldnt crank at all and is still in shop trying to figure it out. This car has been very well maintained but yet it acts as though it has a mind of its own...Any help would be greatly appreciated for I am at roads end with it
#1109 of 1448 Wire(?) problem
Mar 25, 2007 (7:08 pm)
A few weeks ago my 98 Chevy Prizm decided to think it was still on while the key isn't in the ignition. All the exterior lights stay on, oil light comes on, seat belt light flashes at me when seat belt isn't buckled, the wipers work, the air works, & the digitally displayed odometer stays on. At some points when I play with my wipers or turning signals while the car is supposed to be off the odometer arrow moves up & down like the car is accelerating. Since this problem occurred I've replaced my battery which was the original battery & have replaced blown fuses. None of which has fixed the problem.
Anyone have any idea what is going on with my car? I've gotten suggestions but I'd like some more with a little insight as to why, out of the blue, this would happen.
#1110 of 1448 catalytic converter?
Mar 28, 2007 (7:20 am)
i have a 2001 chevy prizm that recently had an emissions solenoid (sp?) replaced. i don't know the exact part i just know it was something to do with emissions. anyway, today i was driving to work & some woman started honking her horn & making gestures for me to roll down my window. she said if my car was running bad to check the catalytic converter. my car is running fine & the engine light is not on or anything. is the catalytic converter something that commonly goes out in prizms or was the woman just a nutcase? thanks.
#1111 of 1448 91 Prism, rough warm idle
Apr 01, 2007 (2:40 pm)
I just bought a 91 Prism LSI with 68k on it.
It starts up and idles great, then after a few minutes of running the idle gets rough and sometimes it even stalls.
What could it be? I have changed plugs, oil, coolant, fuel filter. No change. Oh yeah, the Check Engine Light flashes at idle and whenever the rpm's stay constant.
