I have a 1996 ford ranger 2wd 2.3 engine. when i had the code read it came up with p301 #1 cyl misfire. I was told to replace the coil pack, Which coil pack should i replace? the one clostest to the front of the vehicle or the one that is located towards the rear of the vehicle. My truck has a bad mis and it is using lots of gas. Will replacing this coil pack correct my mis and my gas consumption problem? Please help I'm stumped.
I would replace all of the coil packs. if one goes bad, then the others usually follow. if you don't want to, i would say the one closest to the front. but you can always try different ones by taking it back off and putting it where the other neighbo ... 1996 Ford Ranger SuperCab

You've done all the right things, so piston rings or leaky valve is out of the mix now. Now back to the simple stuff. Change your spark plugs to A/C Delco 41-103 if you haven't already. Don't try and gap them, the iridium will come off and possilb ... 2006 Chevrolet Trailblazer
Have 1995 jeep wrangler-2.5 engine, won't start, have power to coil pack but not past coil pack, replaced coil pack with new one,electrical problem or possible sensor just not sure what to look for,anyone have any idea's? thank's!!!
Most common cause is the crank sensor...It tells the computer when to fire off coil. Cam sensor does this as well but is less prone to failure. Don't change parts because I said so! Proper testing is essential! Test b&c terminals of sensor with ... 1995 Jeep Wrangler
2007 kia Rio Engine shuts off intermittently. History: 1 year ago we had an issue with rough engine and power issues (Approx 150k). replaced spark plugs and same issue. Engine light codes reported misfire on cylinder 3&4. replaced both coil packs for those cylinders and no problems since. Then out of the blue a couple of months ago the engine would just shut off randomly, no bogging or rough idle, just the engine would stop running. this would happen usually when slowing to a stop, making a slow

I have a 2000 vw new beetle that has an eletrical miss specially when i start the car after being cold.the spark plugs and the spark plugs wires were replaced but the miss is still present.one of the coils in the coil pack is a little bit weecker then the rest.the question is why when the engine is cold the miss is worse and the check engine light keep flashing untill the car is warm than the check engine light would stay on.and what is the solution. thank you
Check the resistances of the coils, check both hot and cold, If you have a greater variaton on one of the coils then the other change that coil. The reasoning does not always have to make sense. Logically the coil would be weaker the warmer the engin ... Volkswagen New Beetle
CRAP.............. I have a 2002 Saturn Vue 2.2L. I thought I needed to replace the timing chain, but when we took everything apart, the timing chain tensior, timing chain, and head, plus all the gaskets had to be replaced. We also replaced the spark plugs. We then went out and purchased coil pack modular. When we take the part that the spark plugs plug into out of the engine, and have it upside down, we have spark, when its in the engine the way it supposed to be, we dont have spark. We can not

I have a 1998 Chevrolet Malibu with a 3.1 engine. The control module checked out to be bad and was replaced. The 3X & 24X Crank position sensors were replaced. All three coil packs were exchanged for good ones. I have 45 PSI at the fuel rail. I have sprayed starting fluid into the intake. I have spark across the sparkplugs. It is an orange to weak red in color. However I feel it should be enough to start the engine. The motor will turn over but the car will not start. Please advise....Lou

1996 dodge avenger. 2.0 engine. While driving the car stalled. After I got it home I started checking, and it had dropped 2 cylinders as far as ignition. Both coil packs are good. Someone had suggested replacing the cam sensor. No good. From what I can find, the crankshaft sensor could be a culprit in NO Spark but not dropping one coil pack. Is this true? I am tending toward a bad ecm/dcm computer. Steve
1. Yes, it's true that the crankshaft sensor could be a culprit in NO spark, but not dropping one coil pack. \015\0122. Of course, could be a bad Engine Control Module (ECM). If you can find another one in good condition, test the eng ... Dodge Avenger
