Does it run the same when tank is full as well as almost empty? There is a screen/filter on the pickup in the tank and if it gets plugged up you could have the results that you are getting. Hope this helps. Please rate this. Thanks

The camaro stutters when driving and seems really under powered and fuel filter has been replaced from under neath the car and runs really ruff at lower rpms and takes a bit to eccelerate up to speed


I would check to make sure it isn't running any codes.
Possible issues may be that you are not running on all cylinders. This could be due to a torn or corroded plug wire. You may also have an issue with the fuel system.

Sluggish during ecceleration, loses power


A 16 oz can of SEAFOAM motor treatment into the gas tank.

Purchase SEAFOAM at walmart, NAPA, auto parts stores.

http://www.seafoamsales.com/how-to-use-our-products.html

Around $9.00 a can.
Be careful putting this stuff in the tank, don't spill on the car's paint!

I do not work for seafoam, I use this stuff and it works!

Ive had my fuel pump replaced. Now, after driving for 10 minutes, the engine loses power and stepping on the gas makes it worse. Tech hooked up a fuel pressure gauge and noticed engine fuel pressure is...


if power fine and no fluctuation than the pump itself is problem or problem with filter new doesnt mean cant be faulty also listen to pump if hum goes high /low than pump is surging and is faulty if pump stays steady and pressure test is steady when teted before fuel filter than problem with filter or line

95 geo tracker runs fine but bucks or surges at 25/30 mph slow cruise accelerates like rocket.


8valve or 16v valves, big diff !

bucks, needs a tune up.
surges are too lean .
for surge check fuel pressure.

i think you mean Wide Open throttle has full power
right.?

if yes , the fuel pressure is ok
and the MAF is bad on a 16v
or you have an air leak.

tell more , get more.
