Back in a LS1, Already have a question

**LSWONCOOP** · 11-09-2009, 02:00 PM

Hey guys. I finally got the car. It's an 00 WS6 with a 6-spd. Only mods are custom catback and K&N filter. My question is: there seems to be some power loss at around 2500 rpms. It's mid-rangish I guess. It kicks right back in and runs good after it makes it past that mid-range. Is this normal? Here's a scenario where it happens: I'm at a stoplight, I take off and shift outta 1st at about 4k rpms, I put it in 2nd and put my foot back in it, then it does this weird thing where it kinda takes a couple of seconds to get going. Is this normal? Maybe I just haven't learned how to drive it right yet and I'm use to the GT I was driving before. BTW, the TCS is off...always. Haha. Thanks guys.

Also, the car runs fine otherwise. Supposedly the dealer did a "120 point inspection". Whatever BS that entales. WOT seems to be fine.

Never mind. I cleaned the MAF sensor with some CRC tonight. Runs like a champ now.

Wouldn't hurt to clean the throttle body as well, if you haven't already.

Get rid of that K&N filter, thats why your MAF is dirty and cleaning it fixed it. Clean the throttlebody too like Y2K said. If you need a new filter, go with Amsoil FTW. A search will reveal much knowledge. And welcome to the meaty LS1

I would also change the fuel filter, cost about $12-15. Its located on the driver side, back around the rear tire, just follow your fuel lines and you will see it. Easy swap

Sweet. Sounds like a weekend job. I don't have a shop and I don't get home till after dark nowadays. Don't want to be working on it and holding a flashlight anymore. Not very fun. I hate when daylight savings time ends. Bush shoulda just made it year-round. HAHA

Migh as well change plugs and wires too. Even if he says its new. I would literally just change everything out that you can change. Basically a full "tune up"

Yeah, I probably will. Funny thing was last night when I was at Advanced Auto buying the MAF sensor cleaner the guy at the check-out said that it probably won't do me any good because K and N dipped some MAF sensors in their oil and put them in cars and they ran just fine. I just said we'll see what happens. Man, was he wrong. Bet I put on another 50 hp at least. Any recommendations for plugs and wires? What brand of fuel filter?

That guy at Advanced is a flippin retard! A maf sensor needs clean straight airflow to function properly. It's like trying to tell windspeed from inside your house.
