Bad Startup

[SlappieBooBoo]

Ok so heres the deal I checked my exhaust yesterday and i have a pretty bad leak. I was just wondering what are some of the symptoms with an exhaust leak? Loss of power? Worse Milage? Its right under my seat. Might that be why i smell GAS sometimes?

Now about the start up. At random times. Well usually after it has been running for a while. If i turn my car off and back on the rpms will drop low like the car is gonna die but then come back up. Now i know this isn't normal and i was wonder what you guys think it is. One thing to keep in mind is that i sometimes get a check engine light for a small evap leak, and one for my evap pressure senor. I don't know what the symptoms would be from either of these.

So what I want to have fixed is... No more gas smell. (I can't decide if my evap problems are causing this(i checked fuel lines seem to be fine)) I want my power and milage back, I'm pretty sure this is due to the E Leak. No more dropping rpms durring start up.

Thanks guys

No one has any ideas?

You have a vacuum leak somewhere.

an exhasust leak isnt much of a problem, you will probably smell more gas than if you exhaust was going all the way to the back of the car, so that is probably why you smell gas, but mileage and power shouldnt be a problem, sure you will have slightly less backpressure but unless its the size of a golfball then ehhh, not really an issue but like s14 said check your vac lines, do a leak check with home depot shit.

Ok so vac lines... i'll look that up. But as far as the check engine light concerning the evap pressure senor how do i make it go away??

[mjjstang]

fix the problem, which would be the evap pressure sensor. look up the fsm it should have steps to take.

I'm not sure what fsm is...but i think i will just fix the leak. clear the codes...see if it comes back....hopefully not

fsm is a factory service manual.

if you have an exhaust leak your car will be loud as hell and in most cases noticeably faster too. lol.

yeah...the weird thing is that its only at random times when i'll have the rough startup..
