I am at a loss here, and I was hoping for a little help. My 2001 SS is acting a little....hinky. Hopefully I can explain the problem well enough for somebody to understand.
Sometimes it won't start when I turn the key. The battery is charged, but the starter won't crank. When it does this, all the gages start twitching. Eventually, it starts though.
Then, sometimes it won't stay running. It sounds like it is missing bad, and barely putters at about 400-500 RPM before dying. Much like the previous problem, it will eventually start and run normally.
Finally, sometimes it will just die while I am driving. This is rare, it has only happened two or three times. However, when it does happen it is preceded by a "Service Vehicle" light, not the "Service Engine Soon" (SES) light and then all the gages go dead. Shortly thereafter, the car dies. It may take a few tries, but eventually the car kicks over and runs fine.
All of this happens randomly (or at least it seems random to me). It has done this in the morning, afternoon, and evening. It has done it in heat 90+degrees with high humidity, heat w/o humidity, rain, and just about any other type of summer weather imaginable.
I am at a loss...anyone have any ideas? I have been told that I may have a bad MAF. I have the SLP MAF, does this sound familiar to anyone?

Yea, first off, ditch the SLP MAF for a stocker, Any other mods? When did this start to happen? When was the fuel filter changed? How is the battery looking any corrosion or leaking?
Start with those first.

Clean and tight battery terminals?
Sounds like your loosing power and its having to re-learn the idle when it finaly gets a good connection, check your battery terminals and make sure they are good and tight and also insure its tight at the starter..
J2001 SS, Its not the car its the Driver that matters....

Thanks, I'll check the terminals today. As far as the MAF, I tried to use the stock one the other day, but because of the smooth bellows and SLP air lid, it doesn't seal quite right...and as a result, the car won't even stay running.
The fuel filter is only a couple of thousand miles old, 4000-5000 tops. Other mods are Mid length headers, y-pipe (cat delete), SLP cold air kit, air lid, MAF, smooth bellows, and a local shop (F-Body Central) did a tune with LS1 Edit. All these mods are at least 6 months to a year old. This problem has only been happening for the last 2-4 weeks.
Thanks for the help.

is the check engine light on??? if so what codes are being thrown???
09-26-2008, 04:54 AM #7
no SES lights. No codes. It's a freakin' mystery!

why does everyone always say that the stock MAF is soo much better than the SLP MAF??
09-27-2008, 01:16 PM #9
No clue, but I would figure that just the mere size difference between the SLP and stocker would make the SLP worth it. Maybe the SLP has bad software or cheap construction??? Anyone care to fill us in on why SLP MAF's are bad????

where did the delphi company develop out of? what if my intake says delphi on it??

I had my car tuned after the MAF was installed...I am actually running a little rich. Exhaust smells like gas sometimes. You can really smell the gas when I park it in the garage. My wife also said she saw black smoke coming out of the exhaust the last time I got on it. Of course, that may have to do with the fact that I got almost 120k on the car...
As far as my original problem, I took off my valve cover breather (after market) and put the stock oil cap back on. The car has run fine ever since. Coincidence? I don't know, but she hasn't given me any trouble yet.
Oh and by battery terminals are all good too, so that wasn't the problem either.
Thanks for all the help, I find it very cool that you are all willing to help out like this!

I hope you don't have any more problems, but if you do, check out the positive batt cable real well. My old piece of junk Delco battery leaked acid from the pos post down the cable and all over the frame. i pitched the Delco and put in an Optima after cleaning the cable, and eventually had the same problem. The cable looked fine, but was full of corrosion when I cut the jacket open. My car acted exactly how you're describing yours. It's no big deal putting the new cable in, but it sucks having to buy it from the dealer. Hopefully you're all fixed up, this is just fyi. Good looking car!
