Kia Troubleshooting Questions? Ask a Mechanic
Hi im David.....has the vehicle been checked for vacuum leaks?
around the base of the intake, at the brake booster where the hose attaches to it and on the back of the intake.
ok. have you cleaned the mass air flow sensor? tested fuel pressure? pulled the vac hose off the fpr and checked for the presence of fuel on it?
try that. if fuel pressure is good and no fuel present at fpr hose, then we will go from there.
