Ok, my car has been bogging for ever!!! Ive do leak tests, compression tests, fuel tests, plugs, wires....and then I thought my battery maybe. So I bought a red top and put it in. Dam my car runs sweet! Then after a day or so same exact thing happens all over. So I dissconnectd my battery and hooked it back up again. Problem goes away for a day and then comes back. Every time I disconnect the battery it runs better for a little? Whats my problem here?!!! WTF :mad:
 
Sorry those pics are old before I knew crap. Ive been recurlating for 4 months or so.
Does this mean there is a sensor bad or something?
 
Do you have a logger or know someone that will loan you one? Im guessing it could be the mas, tps, cts, or failing ignition part. Unfortunately, it is just guesses and you really need to see what a logger is showing when the problem arises.
 
Ok im hell bent on getting a logger now. Im just wonding why it runs good then bad later? If it was the mas then it would always be bad right?

Maybe a stupid suggestion, but have you cleaned your battery contacts and the battery terminals?
 
I just bought a red top 2 weeks ago with all new gold terminals. I know every time I disconnect the battery, the computer resets. So after I drive it it messes up reprogramming itself right? I need any suggestions!
