I have a 95 eclipse bone stock. Keeps throwing different codes at me. I've only had the car about 2 months and I've been resetting the light every so often but it's coming on about every other day now. The codes are 64, 32, and 55. But sometimes instead of it being 32 it will be 64, 13, and 55. I've got a Haynes manual and 55 isn't a code in the book but it definately keeps popping up. What I don't understand is why it's coming up with 3 codes simultaneously and yet they are different every time. Only symptoms that something is wrong is there is a bad hesitation at low rpms and it's much worse when the engine is cold. It smokes a little and has some valve train noise. Don't know if any of that helps but any advice would be appreciated.

Haynes manuals are typically incomplete and/or wrong.

PCM Error Codes

Thnx for the link. I went through the codes pertaining to me and breifly rubber necked through the home page. Guess what I need to know is, is there a way to test both the egr valve and the map sensor to see if they are bad? In some of the older posts people complain about a rough idle with code 32 but the car only does that for like a minute when it's cold. Normal in my book. But after reading what a map sensor does and how it works, I'm leaning more towards that being the problem. Never messed with one before though.

In most cases,if the MAP sensor is bad, you'll rev-limit at 4000RPM.
