Services Performed
- Customer states that the vehicle runs rough at idle and runs great after 1000rpms. Verified idle concern. During inspection I used our APOLLO D8 scan tool and found that there were no engine diagnostic trouble codes indicating a misfire. Upon visual inspection of spark plugs I found that they were OE and worn. I also found that the throttle body was dirty and contained oil inside the intake plenum. There is also fluids surrounding the lower part of the intake manifold indicating that there is also and intake leak. Old spark plugs, a dirty throttle body and a leaking intake all play apart in how the engine idles. I verified that the vehicle does have good fuel pressure and that all injectors are good. Recommended tune up, throttle body cleaning and intake gasket replacement. R&R spark plugs, cleaned throttle body and performed throttle position relearn. Idle is improved however vehicle will need lower intake manifold gaskets to significantly restore idle to normal operation. Vehicle will be scheduled next week for intake gasket replacement. Labor includes Diagnosis, throttle body cleaning, throttle body relearn and spark plug replacement.
- Changed engine oil and oil filter. Visually inspected fluids, belts, hoses, brakes and tires. All visuals are within manufacturer specifications at this time. Rotated tires and set psi to 35 front and 39 rear. Reset maintenance light and placed new oil changed reminder sticker in windshield.
