95 burb.... considers napping randomly at stop lights [Expired Topic]
My 95 has just recently started to sputter and rough idle when I get to intersections, I haven't noticed any problems when the gas is applied. It hasn't died completely yet but randomly as I slow/stop at an intersection it starts to sputter out and sounds like it could actually stop. As soon as it gets some gas its fine again. I changed out the plugs, wires, cap, rotor last week with no change. It seems to be getting a little worse every couple days. Happens about 3 times a day while driving around town. Any thoughts? I dumped some injector cleaner in this morning thinking they might be a little clogged up......

Kinda sounds like a vacuum leak or an IAC valve that is not responding the way it should. Those throttle bodies were known for having a vacuum leak under the throttle body, the gasket between the TB and the intake gets real brittle with old age and creates a vacuum leak that is real hard to find.

Is this only when at idle? It drives normally at driving speeds as far as you know?

That's exactly what my dad's 94 was doing. It turned out to be the a/c compressor trying to take a dump. Turn off your a/c and see if it smoothes out. If so, that would be the problem.Gary

This does only happen at stops, on the road when gas is applied it runs fine. The AC is off now that is a whole additional issue, I need to replace the whole front end of the AC. Its at a shop now getting checked out, I was out of ideas and time. I will let you know how it turns out.

Just got a call back from the shop, they said that at the intersections the timing is getting set back to about 2 degrees where it would normally be at 17 degrees. The shop manual says the only thing that impacts the timing lke that is the ignition module and they put a new one in and nothing changed so they took it out.
Picking up the truck in an hour, they give up

I thought the computer controlled timing, not the ignition module. Is the check engine light coming on?

There are no check engine lights and the computer has no maintenance codes either active or in the recent history.
