Default dead spot around 2k **problem solved**

i was wondering while driving today where is the powerband on our cars? I have my 93 se and it always seems to have no power at 2k. The engine runs like a charm (rebuilt her 10k miles ago along with the tranny) other than that i have no complants about the car.

any ideas :?:

That'* just below the power peak in our cars. You may be in a funny spot between gears though.

If i try to give her the beans @ 35 it usually will stay in gear, and eventually get going good.

Squirrelly.. check your MAF, TPS, and O2 readings. Could be the TPS had a sweet spot reserved for you.

On my 1998 L36 I scan a heck of alot of knock reduction at 2000-2400rpm. I'm currently trying to tune that out in my spark tables.

I don't know if your Series I L36 would have the same knock issue as my Series II. Do you get knock when accelerating through that rpm range?

Also, being pre-OBD-II, I don't know how you'd go about fixing that up (other than to run higher octane gas).

If I'm not mistaken Bandit, didn't you have a similar problem and it ended up being the EGR Valve?

This is why we frequently suggest a TB and sensor cleaning. Glad it fixed ya up Squirrelly..
