Check engine comes on, idle raises, smells like gas

Any ideas what this could be?

What code are you getting?

usually these issues are related to vacuum leaks, intake or exhaust leaks and even a bad O2.

Other causes, more rare, but can happen. Fuel injection issue or a sensor issue. Need more info.

Pull the code.

Just so you all know, If I think you're an ******* I will gladly tell you. I'm not your everyday girl, so don't expect me to act like one. And yeah, I do like it topless and dirty!

You can turn the key on off on off on and you will get blinking engine light codes. it will blink a certain amount of times close together for the first number, and then a pause, then blink again for the second number. Should come out with like 24 or 45 or 34 for example. Post those numbers up if you dont have a haines manual and ill check them out for you or if you do have a haines it has all the engine blinking codes in there.

Mine does that in my 4.0L and reading mostly o2 sensors and rich or lean mixture

good luck

ssssh Angel. I'm dazzling them with my stupidity.

Really, I just want to get peeps into the mind set of the basics so they can save some cake.

YJs are Zen relaxation for me.

Back to Tech. I suspect your getting a 02 sensor code. Rich.

Outwornangel is giving some very good advice with the Autozone suggestion.
