Electrical problem
2004 Isuzu Rodeo Question 4 cyl Two Wheel Drive Automatic 56,553 miles

Both check engine and reduced power light constantly coming on, I lose power while driving and can only go about 35mph. Have had both catalytic converters checked, MAF replaced and put back, both TPS' replaced and still have the same problem. At first the same three codes would show up p1515, p1125, and p1295. Then the other day while running the car it began to shut off by itself every once and a while. Then all of a sudden it went from the same three codes to 12 codes. Disconnected battery and when lights came on 15 codes appeared, then when we did the same thing 20 codes appeared. If given a day the car will run fine for about thirty minutes then check engine light and reduced power again. What could the problem be? Could it be the wiring? Or could it be that I need a new computer? Can I get the computer checked out somewhere?

Do you
have the same problem?

I googled the three codes for you and this is what came up. I recently had the same problem with my wifes car and we replaced the TPS and it runs just fiine. The TPS is a dealer only part which costed us 150 bucks. Hope this helps.

We thought it was that too but when we replaced the TPS the car still had the same problems. If I let the car rest a few days it drives fine for a day then after that back to reduce power and check engine. It's as if the longer it rest and no one drives the longer it will go without messing up sometimes it will last 2 to 3 days. Does anyone have any other suggestions?
