Acts up when at operating temp. smells of gas when accelerated, acts normal most days, but when its inclement weather acts up.
If your car is losing coolant or water it could be head problems or head gasket blown,if not losing water or coolant,,then my be distributier cap or leads ???mick
SOURCE: Chugs, acts like it's not getting gas once warmed up. Idle's fine
This problem can be several things. When your engine is cold, your computer is in a "closed loop" and just pretty much keeps the engine running until warmed up. After reaching operation temperature, the computer starts reading all the sensors. If one sensor is not connected or is defective, you will experience performance problems. Most of the time this will turn on the check engine light, but not always. Second is the fuel pump. This too will cause erratic engine problems.

These 4.3L W motors are common for fuel leaking inside the plenum causing them to run rough and smell like raw fuel. The fuel pressure regulator leaks internally, also the injector spider leaks and the two fuel lines feeding the fuel to the spider. You have to remove the plenum and look for the clean spot. Where the fuel leaks it cleans the oil off. Before you try this check your EGR valve. The EGR valves on these get stuck open with carbon and cause a rough idle. Remove it and look for the plunger it is a small round piece that you can push in and out, make sure it closes fully. You can also clean it with carb clean and they make a replacement gasket with a screen in it to keep chunks out of it. Start with the EGR because it is easier. The parts for under the plenum are available at most any parts store. If you have any problems just ask, and if you can not find the parts I will give you part numbers. Let me know what you find I will be back tomorrow.

Hi! I had the same problem with my 88 2.8 Ltr. Had dirty fuel Injectors. Put in fuel Inj. cleaner in gas tank, after a couple of days, runs like a dream,no more problems. Give it a try. Take care,Leo B. [email protected]

Look for broke/ shorted wires on Crank sensor.. thanks
SOURCE: temperature gauge rises when idling
First check that your fans are operating and coolant level is full. If they are, check that there are no leaves etc stuck betweren the radiator and the AC condenser.Last option is a bit more expensive...radiator may be partially obstructed internally (would need flush or replacement)
Egg smell brings me to another potential problem if converter is partially plugged it will raise engine temp as well...the rubber smell is oil residue on block getting hotter than normal and evaporating.
If you work on this yourself ask any techinical questions you have along the way and I'll try to help. Otherwise get the car to a shop asap...overheating in any form can severely damage your engine.
Good luck!!
Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving
