Hello, you only have a problem at idle, not while driving down the road? Is the check engine light on and have you had it checked for codes and fuel pressure tested?
Ok need to do a fuel pressure test to see if the engine is running lean, this will cause a lack of power. Also be a good idea to run a diagnostic check for codes if the check engine light is on or not to make sure you dont have an issue with map/maf sensor or other computer control system. Sounds like it may be just a fuel pump issue from what you are describing. Remove the fuel filter if it hasnt been changed recently and see if it is plugged, you should be able to blow through the filter
Ok should hve 30 psi of fuel pressure there is a test port on the fuel rail on the intake
hard to say since its no longer not running properly or verified fuel pressure
Do you need more help with this concern?
very good, check fuel pressure and such and let me know what you find
no thats only on a diesel application
if it uses one it would be at the air filter housing. otherwise it uses a MAP sensor on the firewall
Yes, but what do you want to test? did you verify fuel pressure was good?
