Sounds like you might need your injectors cleaned up.

Have you tried any injection cleaners ??
Seafoam works great!

Gm does recomend that the fuel system be cleaned professionaly about every 30-40K miles,
as these injectors and the lines get build up and can cause the injectors to clog/stick.

Might also check your IAC.
Idle Air Control(IAC) Testing Replacing for 99+

and Welcome to AF!

had injectors cleaned at a fast oil change shop $79.99
they also did fuel filter and air filter at that time there was no problem about 4months later fuel pump went out replaced fuel pump and plugs didnt do anything with coils or plug wires!
what do you think about this maybe coilos bad but when it starts to shut off it jurks and idle gets rough.thanks

Cleaned the iac and no change but 2 days later no engine idles at 1000 rpm when cold than goes to 500 rpm and motor shakes like hell

Well I wouldnt trust an oil change place to check the air in my tires

The dealership uses a much better cleaning system
Kinda like this.... Napa sells the kit for around $300.


I'd try changing your spark plug boots!
Then if that doesnt work test or get the coils and ICM checked out.

Good Luck

Yes That Would Be Nice But Theres No Place On Fuel Rail To Screw On On The 2.4

[xeroinfinity]

No but they sell the hose and connector(s) needed with the fuel gauge kit.
Yea big pain in the butt

Yea Just Found Out I Bought A Kit From Napa Willmuse This Weekend And Let Board Know After Findings

[1BOSSMAN]

well ran fuel injection and changed plugs and oil again and now its worst any input

[xeroinfinity]

Probly the ICM or coils are bad, get them tested.

Typical when all the heat being trapped under the top cover.

Now I Am Getting Code 0441 Please Help I Know Its Evap Or Purge But Do I Just Replace Them

[xeroinfinity]

A p0441 is - Evaporative Emission Control System Incorrect Purge Flow

Did you overfill your gas tank, or just fill up ?

Evap codes are tricky to track down, check out this thread for more details.
The GAS CAP code!!!!!!!!!!!!!!
