Hey everyone Just wanted some ideas on something. My 88 wagon just started acting strangely lately. it all of a sudden went haywire. I was drving along and everything was adjustedly perfectly and I went in the store and shut it down. when I came out and fired it back up it was idling eratticly and it sort of hesitates now when I accellerate and even at times will shut off in the middle of me driving or when I pull up to a light. What does this sound like? is this a carb problem? or does it sound lie the fule filter etc? remember everything was fine and then all of a sudden poof. I have a new timing chain on it, a new ignition coil, new spark plugs new wires and new cap and rotor. could it maybe be the fuel filter or the egr valve? I am not a carberaution person and grew up in the fuel injection era so I need you guys help. (now you all see why I am switching to fuel injection lol)

Check the simple stuff first.

Check the bulkhead connector for the engine harness. Tight?

Did you buy fuel lately? Cold and Warm temps on the same day? You may have water in your gas. Get a bottle of fuel line dryer and a bottle of in-tank fuel system cleaner. If there's water in the fuel filter, that should take care of that too. Wait until your next tank of gas before tearing into anything.

You should have "felt" my 99 'burban last Wednesday with this bad tank of gas I got. It is of course FI, but it looked like the engine was going to jump out ot the compartment when it first started. A couple bottles of dryer (40 gal tank) [and 1 heated phone call to the gas station] and I can once again balance a nickel on the air cleaner ;) .

Could be dirt in the needle valve or idle passages. Or a stuck neddle valve. I had pieces of charcoal from the canister get sucked into the bowl and clog the jets. The vent inlet didn't have a baffle in it so an inline filter solved the problem.

Could be the dreaded ignition module failure. When mine went, I came out from a store after driving it about 15 miles on the freeway and it just started stalling without any warning that it was failing. Also the EGR can cause weird problems too. One time out of the blue mine would barely idle, I reached under the EGR and moved the diaphram back and forth a little with my hand and it returned to normal. That was several years ago and I still haven't replaced it, it seems fine now.

I guess it could be bad gas, that happened to me in a 1969 Buick duece and a quarter I used to have. It ran like sheeit for about a week, I could barely drive the thing.
