I have an 07 Canyon 2.9 liter, 4 cylinder that turns off consistently when I slow down or make a turn. I've done everything from changing coils, oil change, replacing battery, solenoid, cam/crank sensors, cleaning throttle body & the vacuum hose (that was torn and no longer a tight fit) beneath the resonator box next to the throttle body. Previous codes, initial "fix", sugg'd replacing sensors. Exact same problem persists. ANY SUGG????
PS, this happens inconsistently. It will run fine for days and then BOOM, turns off. It also has an inconsistent rough idle. Please help.
Run a can of sea foam injector cleaner through it. The kind you pull a vacuum hose off the engine and put in the can of sea foam until it is empty. Did you change all the coils and spark plugs?
I did replace all coils and spark plugs.
Had same problem, cleaned the throttle body and never had the prob since. I know it says you did clean throttle body but maybe try again.
