Engine light and smells like gasoline....

Every morning when i start my car or when the car has not been driving for a while, the car starts perfectly, but with the smell of gasoline and im not putting cheap gas in it, i put 93. Then while driving, Engine light goes on for a sec, car holds back, light goes off and car just keeps going. Drives me insane!! I live in New york and i have no where special to take it to, i dont trust anybody.

Help me!

I'd also check the rubber fuel line(s) in engine compartment. The mid '90s models had a run on fuel line "premature aging".

Got your PM. The knock sensors monitor combustion in the chambers, and guide the DME in retarding or advancing ignition spark. If one is faulty, you'd get pretty much the symptoms you're describing, although I'm not sure if it would include the smell of gas. You may get lucky and find that the wiring harness to #2 somehow got unplugged. Or more likely, it has to be replaced, which is about $75 for the part, I don't know how much labor will cost.

Hope this helps!

There are 2 of them, the 1st is for cylinders 1,2 & 3, the 2nd is for cylinders 4, 5 & 6. Cylinder #1 is at the front of the engine.

No DIY's that I know of, but it looks pretty straightforward tho. Might wanna check bimmerdiy.com just in case he's got something on this.

Re: Fisher- ha nice! I'm actually looking to score a complete Thule roof rack with 2 bike trays for $200 from some dude in the Bronx

That I don't know; they should be the same. I would ask whoever you're buying them from.

It has locks included and two bike racks included. You can't get this setup for less than $400 anywhere.

Thumbs up

Nice looking racks, Thule is an excellent brand, come to think about it the price is good, didn't know you were getting so much stuff. One of these days we'll meet up to ride.
