Bogging Down

[suzuki-guy]

when i am in a low gear or like when i am in a parking lot or coming to a stop my truck spitters and sputters but never stalls. It always idles fine and the check engine light never comes on. Here are some things that I have checked, throttle positioning sensor, EGR, ran sea foam throught it, resurfaced heads, new valves, pushrods, rockers, and ran a compression check(which came back normal) It never stalls and still goes down the road fine i was just wondering if any one else had this problem before or knows what it could be. Thank you Cody

Have you tried cleaning out the throttle body?

[suzuki-guy]

just with sea foam and carb cleaner but you mean actually take it of? no i havent tried that yet that would make sense i just replaced the fuel injectors and sprayed it out with carb cleaner but you think it will take more then that? Thanks CODY

sounds like what mine was doing when the crank sensor was going out......do you get any codes?

[superjim]

^^^^^^ what he said.

Check the crankshaft sensors.

Fuel Filter?

Fuel Filter?

 

fuel filter would do exactly the opposite.....bogg while running and fine while idling

where is the crankshaft sensor? wouldnt this throw a code? how expensive is this sensor and how do i check if its bad? thank you cody
