Thread: Bad MPG question

So get this guys, its one of those "i cant believe it" moments lol so today at work we discovered on a customers car that the timing light we were using was faulty -___- soooo instead of using the snap-on "best of the best" light i decided to hook up my garbage cheap light i bought like 5 years ago when i was in a pinch and it was at 12.5-13! So i adjusted it to dead nuts 15 and shes pretty much running like a top. Ive gone about 30 miles tonight and my gas gauge hasn't moved, it miraculously fixed a small stalling issue i have had that i didnt think was related, and overall is running great. I feel like i should advance it a little more still but at the moment cant believe how its running and the situation in general. U guys are the best!

Stock as in stock de red top injectors ? also check the fuel pressure. Return line might be.clogged

Awesome advance that puppy to 20* and have more good time



Stock as in his ECU is tuned for his injectors.

Good stuff, glad you got it worked out.

Ya im gonna advance it a little at a time and yes stock de red top injectors

Sweet, let us know if there are improvements in gas mileage (numbers wise.. not gauge wise)

Lol im at 230 to the tank so far and ill need to fill it up tomorrow but ive only driven it one night fixed so far, should b in the 18's or so which is quite a jump

dont know if this was coverd already but driving a turbo motor NA is probably your problem... when i went to get my turbo rebuilt i slapped on a NA header and downpipe. It was SLOW AS BALLS and wasted hella gas...would take like 60 seconds just to get to 60 lmao flooring it. when i slapped the turbo back on everything went back to normal...

hey guys didn't want to start a new thread but i'm having some bad gas problems too . i was told by my mechanic the last time i went to him (to replace my gasket valve cover ) that i needed to change my catalytic converter . i read online when that part goes bad, your MPG lowers but not sure how bad as it didn't say. i've been smelling gas coming from my exhuast . thoughts?

I would start a new thread, your setup is no where near as close as to the OP's.
