I just bought a used 1997 Mitsubishi Eclipse and now the check engine light is on. I do not have a manual. I checked the oil and it is OK. The fan starts on every time you turn the key. Do you have any idea what else I can look at?

You must have the scanner, or fix it, then drive the required number of drive cycles....

Go to Autozone and have the computer scanned for code/s to find out why the CEL is coming on, this is your starting point -You have a problem within trhe engine management system.

Rent an scanner at your local autoparts (autozone) they rent it for free and "erase" the codes, disconnecting the battery wont erase the codes, you should use the command of the scanner.

good Luck.

i have a 97 eclipse spyder gst... the issue im having is that when i give my car gas it feels as though im not getting any power, like its not getting enough gas. ive already change the fuel injector regulator, which fixed the problem for two weeks. i started my car yesterday and it started doing the same thing out of the blue. ive checked the spark plugs and wires, they are good.. when i hooked it up to the computer it said something is wrong with cylinder 3.. i was told that i should replace the ignition coil pack to see if that would help.. the check engine light is on. i was also told that an o2 sensor is out. im just curious if that would cause this problem or if there is something else i could be checking...

What are the trouble codes retrieved?

If the CEL is indicating, the priority is to get the problem indicated rectified as any fault in the system can affect performance.

Recently purchased used. In order to pass inspeciton catalytic converter needed to be added, along with other minor repairs.

PROBLEM: Runs intermittently rough (stutters) Check Engine light comes on when car stutters.
and goes off when running ok.
Local mechanic has worked on it and cannot diagnose exact problem, but believes it to be either fuel or electrical problem and said it will either need to get worse, or be consistant to figure out cause. Or he suggested that I take it to dealer for computer diagnostics. to pinpoint problem before it gets worse......
I don't want to put a lot more money into car--if problem is not costly to repair, I will fix, otherwise, I am inclined to get rid of car before it starts bleeding my pocketbook.
I welcome any suggestions or ideas.
I mention the catalytic converter because Car Talk said after market catalytic converters do not always work well. That is the only clue I have to go on........
Thank you.

Intermittant problems are very hard to figure out -- let's just go ahead and say say they really can't be solved. Except it would be good to know what the codes were.
You have a fairly old car and if you got it for a good price and the motor is running strong and otherwise in good shape and the transmission and body are OK -- I wouldn't get too discouraged.

An old motor might have just anything wrong with it, and some of it could be inexpensive to fix. If your mechanic is treating you right otherwise, I'd take his advice and hang in there.

Hi there,

Have a scan done to identify the code first and post your findings here.

I've been around the block with Mitsu failures so if it happened to your car you can bet it's happened to mine. I got my little baby in poor condition, so it's no wonder. Anyway, my car had this problem too. Turned out the fuse for the check engine light was bad. I hear its a common problem with the 1997 Eclipse. Good luck locating it. :)

Misfiring codes is an indication that cylinder not putting 100% when engine running
Spark plugs and tune is 1st to do
Check if have spark on all cylinders and coil firing
Check injector and injector pulse
Do a compression test

HI there,

The engine light is a visual indication that there is a set fault code lodged in the ECU, you will need to get a scan done to read this code and this will give us the information needed to sort out this problem, start here.

1996 Mitsubishi Eclipse

My 1996 Mitsu Eclipse won't start. The check engine light comes on and the timing belt turns but thats it. The only noise it makes comes from the timing belt turning, which is not loose. (Note: It stopped running when I was driving it).

So about a week ago my 1990 Mitsubishi Eclipse check engine light turned on so i went home and told my dad about it. He turns on the car and the check engine light is gone and he says it turns off and on once in a while, does not really mean anything. A day after that it comes back but for 2 days straight and the third day i try turning the car on in the morning and it turns on but immediately turns off no more than 2 or 3 seconds later. Try it 2 more times and same results. My dad tries it and same results. He tries again a few hours later when i am at school and it drives fine. Whats wrong with it?

You need to retrieve the trouble codes to understand what went wrong.

The above link explains how to do it.

Hi there,

you will have to get a scan done to read the fault code that has been logged, this is the reason the fault light is on, the code will tell the tech what system is faulty.
