I've been having this problem ever since I bought this mustang I changed few stuff, but I still have it. Hopefully you guys can help. I have a mustang 2002 3.8L coupe and it has the weirdest misfires at times. In the morning when the engine is cold It starts perfectly and It has no problems what so ever, but during traffic and when the engine is warm if i'm driving lower than 20mph the car seems to misfire and shakes a little and when I hit the gas pedal it feels like i'm doing nothing it doesn't take any gas like for few secs then after that it runs. When I get out of the traffic and I go back to the normal speed which is 55mph the car no longer have misfire nor any type of shaking. The 2nd misfire that I get is when I go to the grocery store and turn off the car for about 5-15 mins. When I get back to the car and turn it on it shakes and it seems to have a misfire going on the rpm keeps going under 1 and its not stable at all, but when I push the gas pedal for few secs or mins it depends the car goes back normal with no misfire at all also I smell a very odd smell its like a type of gas, but not gas I don't know how to explain it. That's pretty much it I've been having this problem for about good 2-3 years. The thing is sometimes this car runs normal for like a solid 3-4 months then it goes back into misfiring. Keep In mind that sometimes It doesn't take any gas and it just shuts down I have to wait for the engine to cool off it won't start at all.
UPDATE-- I looked under the hood today because the car was acting up again.The antifreeze coolant somehow came out to some part of the engine and a little on the battery so there's that.
I check the codes this morning here's what I got : p0316 - p0456 - p0174 -p0304.
- The things that I've checked/ changed is :
1.fuel injectors
2.Spark plugs / wireset / coil.
3.Air filter/ IAC.
4.Camshaft/Crankshaft position sensor.
Any help is appreciated thank you in advance!
