We were driving chads 2000 se (l67 swapped), he got onto it and it felt absolutly dead. No power what so ever. I mean the needle wouldnt even move . So i am trying to get some ideas flowing

Tomorrow it is going on a scan gauge to check for KR and more then likely a FP gauge to check that. Any other ideas, common problems where an L67 would just loose all power. (it was fine not more then 3 hours before that, the last time he got into the throttle)

When mine did something similar, the O2 sensor was dying. Most of the time it was fine, but occasionally stepping on the gas did nothing. Either backing way off, or really stepping on it would would bring things back.

He tried easing into it, and going WOT and it has nothing. But yea, O2 is a good thing to check.

Put it on a scanner and everything looks fine

1 degree of KR, full timing
MAF is good, O2 is good, TPS is good ect
All transpermetars are good

So i am thinking something like fuel filter or cat.


It is fine at free rev. And driving giving little amounts of throttle (normal driving). BUt when you get in the throttle at all, no power

Tried new plugs, still the same

Trying fuel filter next, and then maybe a new O2.





Anyone have any input?


It was fine that morning and has been doing it since. (it is actually alittle better now, but not anywhere close to normal). It will give the tires a little spin and then like dogs. It doesnt even have enough power to move the rpms high enough to shift. It like dies at 4200 rpms and the tach just sits there until you let off.



PS--- we washed the car that monring and left it in the garage, i am wondering if washing the engine bay had anything to do with it.

How'd the old plugs look?
Is the cat rattling?

BCS?

Plugged injectors?

Have you checked all of the vacuum lines, in particular at the T under the supercharger snout?

The plugs looked normal except for on every 1 half the plug was normal and the other half was darker. Kinda looked a little strange.

I dont think it is BCS, but i am new to L67s. He is seeing the normal 7-8 pounds of boost.

Cat isnt rattling, but does have 230K on it

Plugged injector, hmm might be worth throwing some cleaner in there.
