1. P0174
2. Car Idles a little rough sometimes
3. Car stalls/cuts off once in a while when I let off the gas. Maybe once every 2 weeks.

Ok well, 1 - I recently got the check engine light. It kinda worried me, but I'm glad to find out after reading around that the car should run and be ok for the time being. I Just got done tuning my car this weekend because I seemed to be getting bad gas mileage so I can't help but think it was something I did.

I changed my plugs and wires (got rid of the bosch and popped in the autolite)
Change my oil (5-30 GTX conventional)
Oil filter
Fuel filter
and my K&N air filter is on order.

The only real issue I can think of that I had was with the Fuel filter. I ended up breaking one of those damn white plastic clips, however I was able to still place the piece in where it was supposed to be and it was secure. I need to check and see if the filter hoses are still secure. And also I started the car, rather....turned the the engine over a few times before it would start because It wasn't getting fuel. I realized I should have turned just the ignition on and off to pressurize the fuel system? Is that correct? Not sure if I could of screwed anything there, I doubt it was an issue.

Now that I think about it, I also took out my air filter out to look at how dirty is was, but I'm positive I put that back in right as well.

So, not sure if it's something I did or not, but I didn't have the error until now, a couple days after the tune-up.

The rough idle, I believe has been goin on since I bought the car 9 months ago, but only until now has it seemed to idle rather rougher. (rpms shoot up and down)

The cut off problem is extremely odd to me, I tested the car before and no errors popped up, and I figured it wasn't a huge issue and I didn't feel like dealing with it at the time. I know, not the best attitude....but I'm ready now. It's been going on for about 6 months now??

My conclusion is some sort of vacuum leak...which I really don't feel like troubleshooting.:shrug: I read around and I'm aware it could be multiple other things but I was wondering if this information made some sort of light bulb go on/off? in somebodies head. I'm sure it's not brain surgery... but I know very little about cars compared to the genious' around here.


:help: Thanks
 
P0174 would be a Lean code on bank 2 IIRC - so like SVTrob said, it could very well be a vacuum leak, especially since that code isnt paired along with an 02 sensor code.

that could also explain your stalling whenever you let off the gas, if it doesnt then I would say your IAC valve is sticking closed, which is supposed to open up a little but when you let off the gas to allow just enough air into the intakes for the motor to idle.
 
Yeah, I forgot to mention it was the "system too lean bank 2" code.

I was talking to a mechanic buddy at work, he suggested to was my IAC and to check to make sure I didn't mess with my O2 sensors.

Thanks guys, I'll check this stuff out.


btw the check engine light went off... we have a rogue
