crossed plug wires Like above only will explaine.. When you were doing the tune up you either turned the distributor or mixed up one of your wires unhook the coil wire and get a friend to turn the engine over in bursts you check the timing marks on the crank when they are both lined up you either have number one or number six pull the distributor cap off to see where the rotor is pointing at, it should be the number one spark plug wire. If it is not there is your mistake go from there and follow the firing order that should be marked on your intake manifold .1-8-4-3-6-5-7-2 Wayne
Running rough? Hard starting? reduced fuel economy? Recommended mileage from owner's manual?

Did they replace the MAP sensor? If not, good chance there's your problem.
one of your problems could be in the injectors they maybe putting to much fuel.
check for other possibilities, tuneup, ignition
Read through the "Related Question" that discusses a common problem with the Windstars and rough idle - check engine codes P0171 & P0174. That might be part of your problem too...
The v6 engines have valves burn out constantly, which will cause both the damaged cylinder and the one across from it to misfire.
Sometimes an ignition coils will break down under heat and not fire properly. Start there and see if it helps. Billy
Check the air filter, fuel injectors, EGR valve and temperature sensor.
You may just need a tuneup. Could be a number of things. Dirty fuel injectors, vacuum leak, etc.
Check the motor mounts.
There can be several things that will cause your 2003 Chevy Malibu to run rough and not shift into fourth here. The probable cause is a lack of fuel. Due to a bad fuel injector.
I'd start with a basic tuneup if it has not been done in awhile. Then I'd clean the fuel injectors.
I would look into a stuck open, or jammed Egr Valve.
Check the EGR valve. Sounds like serious vacuum leak. Reminds me of when I left brake booster vacuum hose disconnected...
You may need to adjust the carburetor. It sounds like it's running too rich.
I would suggest a new set of plug wires.
Probably in need of a good tune up.
Sometimes a piece of carbon will get caught in the EGR Valve. If is is hard starting, idles rough, and the brakes are hard, check the EGR Valve, it probably has a piece of carbon stuck, keeping it open.
Perhaps you have a leak in your transmission. Check the transmission fluid while the car is running. DO NOT check any other fluids while the engine is running.
If it is slipping in gear or any out of the ordinary rough shifting.....
after start car smell gas why?
raging, riotous, rough, ruinous.. :D
All of the above
The EGR valve on a 1994 Chevy 1500 is located on the top of the engine. If the valve becomes stopped, the engine could idle rough or stall.
