Question about 1995 GMC Sierra

1 Answer

1995 GMC 5.7L TBI, I got the timing set and the truck to run but sputters out after a short time. If i press on the gas it seems to bog the truck down and put too much fuel in as it made a fireball an

The injectors were just replaced along with the fuel filter, have a new fuel pump but haven't installed yet. Truck ran rough and sputter/died before replacing intake gasket. Finally got it to start after setting timing but now it barely runs and can't push on gas or I get a fireball out the throttle body.

My 1999 GMC Jimmy kind of sputters or bogs down when I press on the gas pedal and doesnt get full power until I reach a speed of about 30-35mph.


Try the Mass Air Flow Sensor if you are lucky cleaning it will solve your problem if not you will have to change it .I had the same problem took out the MAS cleaned it put it back in and no more bog.

it is definately a fuel problem, if you press gently it speeds up step on it and it just bogs, i think it has sommething to do with the ecm that controls timing and fuel at the TBI (throttlebody injectors) not a filter, i put a new pump,tank,filter and cleaned out the fuel lines and still could not cure the problem, then i heard of a few thigs that got me thinkin but when i was gonna tackle it a guy said he wanted to buy it so i told him the issue he didnt care and i sold it. but those were the only things left to do.

I would say it may be the distributor, I would start there first. You may want to try a tune up first to see if it helps and I would definitely get my battery checked out since winter is approaching and it has been run down a few times. hope this helps tim

Check or replace your injectors if it is a TBI, run some injector cleaner through your gas tank if you have a MFI or CSFI injection system.

Check ignition timing, timing chain, fuel filter and fuel pressure after you change it. ( if the filter doesn't solve it)

Could be the TPI Sensor or it might be a touch out of timing.
