Please run down this guide and report back.

I bought my car as a salvage 7 yrs ago and now have over 211,000 miles on it (2.0L). I made the proper fixes as they came up. Now my check engine light came on and Autozone says it coded P1072. Replaced the plugs,gonna do the wires next.Any suggestion as to whether I should work on replacing the O2 sensors next? The only other time I had a light come on was when cylinder 1 was misfiring. I replaced plugs and wires and the problem was gone. Cars been great to me,and I'd like to keep it running okay and pass NYS inspection this April. Thanks for your time and compassion at what you do!

What was the description of that code...it is not a misfire code.

The service person said that the fuel system for bank 1 was too rich.Said it could be the Mass Air Flow sensor,O2 sensors,fuel injector problem,or ignition misfire-repair. When the correct fix is done,will the check engine light reset itself? Thanks for the swift response!!

Okay the code was a po172, 2 numbers were transversed.
try cleaning the mass air flow sensor first

I havn't been on line here, sorry for the delayed response..

I replaced the plug wires and started taking apart the air intake assembly to find the mass air flow sensor. Is it just off to the right of the butterfly throttle mechanism?It has a plug of wires attaching to the top of it? If it is,is it easy to take off and inspect?I heard that the part is very delicate?! The car seems to run fine,but every once in a while at a redlight after idling for a minute or two,the RPMs will dive and then surge.Thank you again, Jack.

i recently bought this car from an auction the service engine light wasnt on and when i went to pay for rest found out it was on. as of today when the engine get hot the transmission seems to knock out of gear and goes way past 4000 rpms when you go 55 mph. if you let cool down restart and put back and gear you can drive it again. we flushed ratiator was disgusting and oil light flashes on and off every once in a while but now just want to no why it wont go past 25mph without jumpin out of gear.

Sounds like your car TCM went into "limp mode" to protect further damage to the vehicle. First off, I would like to know what code that the computer stores.

You may have to replace both speed sensors and the TCM itself. But first find out what codes you get.

i just bought this car and the next day i see the engine light kept popping on after i drive for about 30 mins. (only sometimes) so my question is would you happen to know what that might be? or why it may be cutting on and off? did i pay a lemon?

You can check for CEL yourself. Be ready with your writing instrument and perform the "key dance". Insert the key into ignition. Turn in to ON-OFF-ON-OFF-ON, and read the codes from the odometer display. Report your finding.
