Weird problem

change the air filter

I've never heard of an exhaust fan, that's like blinker fluid. I would think that the"e-fan" is an electric fan. If you take the stock fan off the engine and put in a dual electric fan you will gain 10% to 15% horse power. To get the right balance you need to make your engine breathe better and putting in a cone style air filter from K&N or even some other company. then bigger exhaust diameter and muffler. you might want to chance the mass air sensor also. I have done all of these things to my 2000 GMC Sonoma 4x4 W/ the 4.3 V6. and its very fast and powerful.

fuel filter?

shouldnt be, the dealership "said" they replaced it...

I have driven it sry on occassion b4, but I filled the tank since

air filter? perhaps if you disconnect the battery for a minute it'll clear
all codes and be fine again for another 93k. it's cheap and if codes
reappear you're not out a dime.

wasnt throwing codes, and besides, its a K&N filter

it was the fuel pump, and they're replacing under warantee (75K mi from date
of purchase (Aug 2000) w/ 24K Orig miles.

congratulations

well, now it runs awesome, and I have a sorta dual exhaust setup (duals from
the cat) wanna add headers and make it a TRUE dual setup, and maybe tweak
the engine :)

ok, now I have a different questionIm looking to make more HP Mods to my
good running, yet high (highway) mileage 1998 Sonoma 4x4I have dual
glass-pack mufflers and stainless steel tips, like I said before, its dual
pipes from the cat, and a K&N filter, plus I always get the Mobil-1
Semi-synthetic oil change...

what else can I do?
