My 3400 idles good, when i rev it and hold it at a constant rpm it begins to stall out and the fumes could kill you. If I drive it like this it runs like a bat out of hell but when I get to a constant speed it starts running like hell, when i give it a little throttle it responds good, but when the constant speed comes back it starts running bad. If I drive it like this for say 10 minutes my check engine light comes on and the car instantly runs great, but doesnt seem to perform as good or pull as hard. Any ideas what this could be?? THanks

do you have aldl cables?

What is that?
ALDL= Assembly Line Diagnostic Link Cable

Its basically a cable that plugs into your OBD1 diagnostics port and the other end into a laptop. It allows you to view real time data that streams out of your OBD1 port in your car. It will also give you information on your car's sensors while in action. Also, you are able to save a datalog of your cars engine behaviour. The datalog can be uploaded onto this site and this will allow other people to analyze the data and give suggestions on what might be wrong. There is more information here:

I bought my cable from here:

The cable came with a bunch of bundled software as well. Hope this helps!
