Go to AutoZone or Advance Auto Parts and they will run a scan for you for free. From there you get a code and a list of possible problems that cause the check engine light to come on.

A check engine light could be anything. It is a problem with a sensor or electrical unit. The ONLY way to tell is to have a scanner put on it and run the engine codes

SOURCE: engine

Check if engine is running too cold or hot on temp gauge.
If so replace the engine cooling thermostat,
it will alter what the computer thinks engine is doing.

SOURCE: check engine light is runs ok

You can read codes without a scanner on the 1995. You have to turn the switch on the PCM (powertrain control module) which is by gas pedal near the floor under the dash. The switch is turned with a small screw driver. Get a Haynes manual or go on internet for procedure and codes. You read the flashing service engine light to get and erase codes. Or, do as other poster said, get an OBD-II code scanner for $80, or go to parts store (Advance or AutoZone will do it) and they will read the codes for you. If you use a code reader, the port (plug receptacle or DLC) is on the passenger side under dash near center of car, near floor, on other side of PCM. You have to pull off a trim cover piece to get to it. I think 1995 is the last year for reading the flashing light and all cars from 1996 on must use OBD-II scanner/reader.

SOURCE: Engine shudders when idling in gear, check engine light on

Take a run into Autozone, or Pep boys, or similar big autoparts store and they will do a free code scan, to point everyone in the right direction instead of guessing, and throwing parts at it. If the fix isn't obvious after codes recorded, get back to us with code(s) and will help you out if still needed.

When I push the gas on my car it won't go past

The car runs fine after it warms up? Is it running with the check engine light off? But it does come on with the key before the engine is started? If the coolant temperture senser is bad ( or disconnected someway) the check engine light will be on but the car might run OK at normal operating tempertures. Have the car checked for codes. It's OBDI so you might have to find a service provider that can ceck the codes on this pre OBDII car. If it turly runs good at normal operating tempertures and the transmission is'nt low on fluild then the coolant senser does'nt always turn the check engine light on if it's bad and still reading something but wrong. Truly running good and the coolant is full ( all the way). chage the senser and see what happens as thier cheap and easy to change with commn hand tools.654437604.jpg

Service engine soon light is blinking, runs rough, light "ticking" at low RPM. seems to run O.K. at 40 to 60mph.

When the check engine light is on, that means there's a problem that should be checked. When the light is flashing, the system beleives that something serious is wrong and if you continue to drive the car, you could cause serious damage. That being said...

You need to go to the dealer or find an auto parts store that will scan your car for free to get the OBD2 codes. AutoZone does it for free. The code(s) may give you any idea of what is wrong and possible sloutions.

Here is a website with the codes and definitions:

Service engine light

service engine light can come on for any number of reasons anything from a sensor failing, to running to rich or lean, or even a misfire

if its on there is something wrong

the best thing to do it to have a code reader put on it to find out what the code is for.
