a friend of mine has a 1989 chevy s10 2.5 ltr 4 cyl.

it pings when i drive on the highway and when i go up hill and give it some gas it bogs out is that my timming? it acctually pings all the time but really badly on the highway. it looses all power and doesnt accelerate untill i let off of the pedal

Not unless you recently changed the timing, check the O2 sensor it sounds like its running lean

if it was a sensor would a check engine light come on or at least a code on a scanner?

as long as the voltage is changing but still reading rich the check engine light probably wouldn't come on with those older model computers. Its just a suggestion you should probably check your timing first though just cuz its the easiest to check. dont' forget to disconnect the tan wire in behind the plastic cover on the top of the firewall when you do check the timing.

when you disconnect the tan wire it sets the timing down to base timing otherwise you'll never get the right timing cuz the computer will constantly be changing it. Its like pulling off the vacuum advance on the older distributors. It should have a connector under a black plastic cover on the firewall, I think it covers either the blower motor or the wiper motor. and to find out what to set the timing at there'll be a white sticker somewhere under the hood usually on the rad support or the under side of the hood and it'll tell ya where to set it. Good luck man!

Just worked on an 88 or 89 S15, the Tan/black wire was under the glovebox.
