Question about 1993 Geo Prizm

1 Answer

I have a 1993 geo prizm,it curently has 176900 miles on it. My problem is that it seems to be lacking power, it sometimes struggels to get over 50. It also gets awful gas millage. I have had it for about 6months and over that time have replaced the spark plugs, air filter, and fuel filter. The problem still is there. Does any one have any ideas?

I suggest you do two different tests. One is a compression test the other is a back pressure test. Compression is for the motor and back pressure is for the catlitic converter. Both take special tools to do and each set costs about $100 to buy. So if this is going to be a one time deal just take it in and find out what's wrong but if you want to buy the tools let me know and I'll walk you through them.

Power streering leak, smoke under hood for 1996 Geo Prizm

Yes , power steering fluid will smoke if it gets on a hot engine, especially on any part of the exhaust system. Barring anything else wrong with the engine such as a coolant leak, and the engine running OK otherwise, I would say that the smoke is from power steering fluid dripping or getting blown on the exhaust by the fan.

GM uses a curcuit board design between the plug and the lamp(part of the rear light asm.) they stink, they corrode over time and fail. Not economical to repair, better to replace. consider an OEM replacement. The aftermarket ones don't last.

1993 Geo Prizm lack of horsepower

Clean the mass airflow sensor (or replace it outright) and change your oxygen sensor. Those are very big contributors to fuel mileage. Also, verify that the new plugs are gapped correctly.
