First off welcome to the site and it's great to have another fellow 98 in the club house.
SLP MAF is the problem - there have been many reported issues using aftermarket MAFs. The stock one is actually a great one, good for up to around 500 hp cars. I don't hate all SLP products but the MAF is a known issue.
Do you have a stock MAF or know a buddy that will let you use his just for a test?
One more way to help determine is disconnect the wire harness at the MAF, let it run on the defualt density tune. See of it helps or makes it run worse.
Also I don't see mention but are you running a K&N filter or something like it?

maybe your transmission is going out? any more details on how your car is driving and any other mods youve done would help...

Welcome Red. I have a 98 also. How many miles are on her? How was she running prior to installing the SLP? You say it's been acting up for a whille now- do you remember when it started?

thanks, 139,XXX mi ive had the car for 5 years, and it hasnt been right for a while say a couple years. just thought it was a bad mas air sensor or just needed a tune up, but not the case.

It hasn't thrown any codes?

yeah smog pump, but that should'nt have anything to do with it. right?
02-22-2012, 02:21 PM #10
dunno about smog pump.... Could it be a bad cat??
02-22-2012, 02:57 PM #11
well when i put on new exhaust think im takin it off.

where at in Ohio? It could be a few things really. The best thing is to log the car if you have access to a scanner that will let you see live data. See what your fuel trims look like and things like that. What you're describing does sound like it could be a plugged cat to me. They almost act like an engine brake and make the car have next to no acceleration. Either that or it's loading up with fuel but normally if that's the case there will be other symptoms.

I agree with everyone else. Sounds like a clogged up cat to me.

thanks a bunch, just received slp exhaust today does it need 02 sensors installed?
02-24-2012, 03:46 PM #18
yes, you need o2 extensions. most vendors carry them.

The cat 02's can be eliminated with no adverse performance effects.
You will get a cat code and a SES (service engine soon) light but that can be turned off with a tune.
