Re: Trouble With S10 Motor 2.8
Ignition timing being "way out" for no aparent reason, could be due to a timing chain with excessive slack allowing the chain to "jump" a tooth on the crankshaft gear. Have them check timing chain slack and valve timing. Timing chain slack should be no more than 12 degrees.

Re: Trouble With S10 Motor 2.8
the same thing happened to my s-10.
it turned out to be the distributor was damaged due to a cracked motor mount. while i went up a steep hill the engine lifted and hit the fire wall causing the dist. to get damaged.. well thats my story...but i did replace the timming chain first before i discovered this bad engine mount and dist. gl.
