What causes a 89 4x4 gmc Sierra to t bog down when your cranking it up and driving at low speeds

SOURCE: 1995 GMC Sierra

check you ideler sensor i had the same problem on

SOURCE: engine bogs down at 3500 rpms and low trac and or abs light comes on

You are spinning your tires ... read your manual ... shut off the traction control .... spin away!

SOURCE: bogs down on acceleration

buy 2 fuel filters. buy can of SEAFOAM at parts store. use 1 f filter to replace old one(you'll probably see old looking gas, with an odor).Pour SEAFOAM into tank. fill up with PREMIUM gas. after about 100 miles change out fuel filter 1 last time..add SEAFOAM every 3-5000 miles and you should be fine. the ethanol in the gas turns to goop and adds water to your fuel, and puts carbon on your valves and through out your emission and fuel system. The ethanol will be alright as long as you follow these instructions. and the SEAFOAM will keep you from having line freeze up in the cold months ahead, and will give you better gas mileage. good luck.

Testimonial: "OK I'll try it."

have it tested using a manual gage if still low then main baring ore most likely bad that would mean a over hall if is really low and bearings bad should be making rattle noise when started up first few seconds

Testimonial: "thanks alot.truck is not making a rattling noise.we did check it with a manual gauge.it read about 10 at idol. press. gets better as you incr speed"
