I think it's a vacuum leak. Check the little rubber hose connectors and the PCV valve and the EGR valve and the mounting of the air intake. With the engine idling (you might need a brick on the pedal to keep it idling) probe around the air intake with propane. When you squirt propane into the leak, the engine will go faster.

2001 jeep grand Cherokee 4wd won't start after replacing fuel filter


If it ran prior to the filter replacement, it will most likely be a filter issue. Installed backwards? You have to allow fuel pressure to build back up and fill the new filter before it will start. You can try cranking the engine while applying the gas pedal slightly to see if it will start

Sputters at full throttle and wont idle


Run pressure test on your fuel injectors. Fuel pump might not be suppling enough fuel line pressure.

fuel pressure should be 35 - 45 psi.could have faulty tps sensor.could have intake vacuum leak or ignition timing valve timing off due to worn timing chain.do engine vacuum test replace all vacuum hoses bad leaking egr valve diaphram or gasket will cause engine run poorly.

When i try to start my 99 vw passat gls v6 it will barely start and stay started for possibly 5 sec with no presure on gas pedal if i keep my foot on the gas it will stay running but the rpms wont rise...


it hard to say there few things that could cause this but sounds like it a Fuel issue
Possible bad fuel pump totallly clogged fuel filter bad injectors Out of gas etc.
first thing you need to do is check your fuel pressure ( I bet it be low ) if it low check fuel filter if fuel filter good replace fuel pump
If Fuel pressure is within Specs then test the injectors
if Fuel pressure is ok and injectors test out ok then check ignition system (spark plugs, coils, module etc)

Describe your trouble shooting 91 gmc truck Problem Truck will start it won't idle you have to pump gas pedal to keep it running but it is fluttering the whole time. unhooked vac line to map sensor it will...


test fuel pressure by renting a fuel pressure test kit from schucks or auto zone then turn key on then off if it hits 50 psi it's ok if it drops below 20 psi in one minuter then fuel pump is bad. if it has throttle body injection then replace the injector or pull it apart to see if it is plugged.check oil pressuer switch behind the distributor to see if it is bad it will cause it not to run if defective.

When I acelerate my car wants to choke


I HAVE PERSONALLY CHANGED A FEW THROTTLE POSITON SENSORS IN THESE VEHICLES. BUT BEFORE YOU DO THAT, TRY SPRAYING SOME CARB AND CHOKE SPRAY IN THE THROTTLE BODY WHILE THE CAR IS RUNNING. YOU MAY HAVE TO HOLD IT AT A HIGH IDLE SO IT DOESN'T DIE ON YOU. THIS SHOULD HELP TO REMOVE THE CARBON IN THE THROTTLE BODY. IF IT STILL WANTS TO CHOKE, THEN CHANGE THE T.P.S. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK
