SoI was on my way home when my truck started stalling out when i approched a red light. It does not stall out when i am accelarting. can anyone help???

 

did the battery light in ur dash come on? maybe ur IACV is set to low? also check that the sensor on ur throttle body is connected n not broken in appearance. just my suggestions since no one else has said anything yet

 

Missing some information like: Make/Model/Year etc...that would help out a lot.

 

its a 1989 chevy silverado k1500. 5.7 L 350 small block engine.

 

Did this just start happening or has it worked up to this? I have the same truck, but '91 and it was doing the same thing with no CEL's or anything. Ended up being the fuel pump. Kid that I got it from ended up doing some crazy crap to the truck, diagnosing it HIS way....lulz....anyway, but that's how it started, then ended up being very hard to start. If your truck starts taking firing up/shutting off randomly try spraying brakleen down in the intake and seeing if it continues running-if so, it's the pump. Hope this helps.

 

the spark plugs are all rusted. if i get new ones will it help??

 

doubtful, just put a dab of oil on the ends (eloctrodes) and put them back in. should fire up with no hesitation then

 

It might not help fix the problem (depending on what the problem actually is) but if they're rusted they should be replaced because that means they're probably way overdue.

 

ok thanks. so how do i fix/check the throttle body sensor thing? where is it?

 

come on man you ain't a real redneck if you cant find yer tps sensor. It is on the outer case of the throttle body. A 2 wire sensor, a potentiometer.
