Hello everyone.. I got a quick question about my 04 LS V-8.. Why do I smell fuel when i Accelerate on the gas peddle ?? it doesn't happen if im just taking off from a stop light, it happens when I try to pass a car and really get on it to gain some speed.. like i said when im just driving normal speeds around town, i don't smell it.. :confused: Milage on the car is 42,315

I'd appreciate any input here TY !
 
Misfires (usually due to marginal COPs) can cause a gasoline smell, but I wouldn't think that you could smell it inside the car while moving more than a few MPH.
I' look closely in the engine bay for any fuel leaks at or near the fuel rail, and I'd check the fuel filter for leaks. I am assuming that you check engine light is not on. If it is on, there might be a problem with the evaporative emissions system.
 
No, the CEL is not on.. and it drives fine, I don't feel a stumble.. but lets say if i did, what does that mean ?? Also the fuel filter is located right beside the front drivers side, can i just crawl under the car and see for myself if it's loose or leaking fuel ??
 
yea, I've had to replace coil # 3 and 4.. due to ETC fail mode
 
A lot of times it jumps around to the other coils so its best to replace all 8 together.
 
Yea, I took my car in to the dealership back when i was having problems with the ETC fail mode.. needless to say, my car ran like a champ that day and she passed the stress test with fly'n colors :rolleyes: So they wouldn't replace the coils.. I had my uncle replace the two that were needed.. So far, the car runs fine, except for the smell of gas when i Accelerate, I have to really get on it for that to happen tho.. as my for milage, 42,322

:give lol
 
Well they don't call them the stealership without reason.. ;)

I would just check for leaks (like around the o-rings at the injectors and fuel lines at any connections.. Also check overall condition of the lines) and if that all checks out, I wouldn't worry about it until you get a stumble or CEL.. :cool:

I would suspect that they didn't really do the stress testing. It would have picked out the bad coils.

I have no idea where to begin.. Heck, when you said o -ring, you could be talking about onion rings for all i know.. that should pretty much give you an idea that I'm a female ;) I will tho, pass this along to my uncle !!

I watched them do a so called stress test for myself.. I'll try to explain what i seen the best i can :eek: The guy plugged in a cable in the same spot where you turn your check engine light off, as the car was running, he sat in the driver seat looking at a bunch of lines on his laptop. he said everything seem to be running normal blah blah blah.. he did that for about ah 30-45 mins. he even took it for a test drive and like i said before, the car ran like a champ that day, just my luck.. so they charged me $ 40.00 and sent me along my way !

Lol.. An O-Ring is a gasket that 'holds' the injector (thing that sprays fuel in the cylinder) in place and provides a seal..

That's not a stress test.. He was checking for misfires.. I would say try a different dealer because this one didn't know what was going on.. The coils must be pulled to do a stress test..

That is not a stress test at all.

To do a stress test they have to take the coil covers off and hook an oscilloscope to each coil. It's pretty involved.

I had a feeling you were going to tell me that ! So, Can i call up the dealership and request them to do the stress test seeing that the Coils are under warranty up till 100k miles ? Or will they give me a hard time, due to it being a alot of work for them ??

thanks everyone, I do appreciate all the help here :)
 
p.s. why would they check for misfires ?? does that anything to do with the coils ?

I'd find another dealer.
Then print out and take these two documents with you.
