My holden commodore2007ve berlina has a problem when accelerate or going up hill has some hesitate or cut of fuel 3 or4 times while driving but I slow down every thing become normal


Hi This issue really requires a scan tool ( advise take to holden). There has been some cases where there has been an issue with the throttle body, this may not be the case with your's but its a good start point. if the throttle body checks out ok then i would require more information . Just another point are you sure its not fuel related it didn't start faulting after a recent refill. This may only show faulty under load.

What engine, what year model? When you get down to about an 1/8 th of a tank pour a big bottle of SEAFOAM gas treatment in you tank. Then go run it out at high RPMs low gear our 100 mph doesn't make any difference. What this will do is clean your fuel injectors and plugs. Think of fuel injectors like a bottle of wind spraying fuel at your spark plugs. If the nozzle on the bootel is plugged it won't mist well, same with fuel injectors slow city stop and go traffic leaves carbon deposits on the "spray nozzle" this will cause hesitation in stop and go. If your savy about throttle bodies if it has more that 80k you need to pull it and clen it. Throttle body plates and intakes+ the senosors that go with it really get carbon up bad. Make sure you use the throttle body cleaner and oxeygen sensor cleaner exactly where you should this one project you cat just brake fluid to clean with. Hope that helped, oh 3rd possible but not likely cause fuel filter slightly plugged. Send back data on miles, size of engine, year, make, If this doesn't solve your problems, do you have any check lights on? Bret

2000 alero gas pedal hesitation as well as shut off when slowing or stopping


Usually the problem of hesitation is caused by a faulty throttle position sensor or low fuel pressure, and stalling is a dirty throttle body or faulty idle air control valve.
Is the check engine light on ?

My 1998 S-10 is not getting gas to the throttle body. I can pour gas down the throttle body and it will turn start and I am able to drive for miles. Once I turn it off, I have to repeat the process of pour...


when you first turn the key on you should hear the fuel pump run for about 10 seconds . this primes the fuel system .If you do not hear the pump run then you need to check the circuits for the pump
the fuel pump has a fuse and a relay that is use to power up the pump . you should check the fuse and if they are ok then switch the fuel pump relay with a like one in the fuse box (horn relay is the same as the fuel pump relay ) I think the fuse and the relay are both in the under hood fuse box on your truck . If these all check out ok then you need to check for power and ground at the fuel pump connector . if this checks out all good then replace the fuel pump . some times if you think the pump is not working you can bang on the gas tank with a rubber mallet this may move the pump winding off of the dead spot and the truck will start ... but this is not a fix .. just a way to get it started to move it or take it to a shop

When ipush on the gas for take off it hesitates slightly but picks up speed great


Hesitation is usually caused by a dirty throttle body or a bad Throttle Position Sensor. I would try cleaning the throttle body first.

NEED TO REPLACE MY THROTTLE POSITION SENSOR BUT CAN'T FIND IT ON MY TRUCK


Hello. The Throttle Position Sensor (TPS) is on the outside of the throttle body assembly. It's beside the throttle plate inside the throttle body. Once you remove the air cleaner from the throttle body you will see what I am talking about. I hope this helps, please don't hesitate to ask any other questions about this.

2004 ford taurus hesitates when I hit the gas?


this is happening because of your fuel pressure which is slowing down when you open the throttle to the intake manifold. you are losing fuel pressure somewhere from the gas tank and the fuel rail. do a fuel pressure check test. that might do the trick.

Perfect Idle, no Codes, but stepping on gas causes hesitation


i would try cleaning mass air sensor, its mounted in air duct between air filter and throttle body, they sell the cleaner at auto parts stores, also as stated bofore make sure the intake pipe clamps are tight and it's not cracked, if that doen't fix it i would investigate a fuel pressure problem either a weak pump or problem with regulator
