It just seems to do it when it gets hot. It's not pinging and I hear no backfires, just the exhaust making like a thump noise when it misses. I think it's only 1 cylinder because on the highway I could hit it to WOT and it would act like it was one cylinder. I took off my smog system a few months back so it's not the EGR. I am just going to get new wires. DMoriss, I have an Accel distributor cap and rotor on it and I am sure they are fine for only having 25,ooo miles on 'em both.Also I replaced the fuel filter over a year ago with a Wix. How long do they last for? Thanks all I'll let you know tomarrow. Steve

Right on, he could do a power balance test, to see if it's just one cyl. (indicating plug/wire/injector/etc. pertaining to one cyl) or random misfire (indicating the ignition/injection/etc. system as a whole).
Like dmorris said, sometimes it's hard enough to pinpoint an intermittent problem in person let alone on a bulletin board. Try the power balance test, and try to narrow it down and see if it's just one cyl that's the culprit.

|87442lover||what gas are you running? try 93, if its pinging then try a higher octane, I had a problem like this and it turned out to be my fuel filter, the car ran fine until high PRM's and then it would miss and buck back and forth. Lots of other stuff to check as well, you try checking the EGR??|

|dmorris1200||Well there's only so much we can do online. Is it fairly common for a 'borderline' set of spark plug wires to act up as soon as the winter weather sets in? Probably yes. I see quite a few cars come in to the shop with rough running conditions as son as the winter sets in and it turns out they just need a tune-up. If you know the wires aren't 100%, I would say get rid of them anyway. How do you know for sure that it's only one cylinder missing and not different cylinders randomly missing? I had a miss one time that was driving me crazy. I would atart car, take off, then after driving for a while would just start bucking and missing. I was pretty sure it was a spark problem because it was a sharp miss as opposed to a 'bog' and as it got worse she would sometimes backfire out the exhaust which also lead me to believe she wasn't igniting the fuel consistantly and dumping raw fuel into the exhaust. Problem was my wires all seamed ok, plugs ok, and I just couldn't seam to trace it to any specific cylinder. It turned out to be the distributor. I replaced the distributor and she ran like a top. Now your distributor may be fine but the point is there are so many posible 'maybes' that we can guess at especially since your problem seams to be intermittant. Your just going to have to take some time and try and narrow things down. I would definately get rid of those wires either way. Have you checked to make sure your fuel pressure is within spec? There are so many 'basic' tests that would generally be done as soon as it came into the shop just to rule out certain things.|

Ok help me! I just got through driving on the interstate highway for about 2 hours and it is acting up again.
I think I know the prob but need the extra help. I have 8.8mm Accel Radio Supression wires. I have had them on my car for aver 2 years. The last time I changed my plugs was about 3 months ago in which I accidentally removed the spark plug clip thing in the boot and had to re-crimp it. And also in which I had to cut some of the boot off in order to get the spark plug connector to clip on the spark plug. Could this be the reason my car is gradually getting worse? If so would it just spit and sputter as it seems in only 1 cylinder at low RPM's with max throtle before downshift?

What do you mean funny?? Funny how?? What's funny? Funny like a clown, what am I here to amuse you and make you laugh? What do you mean funny??
But seriously, the great reality of this site is there's a lot of knowledgable guys who help out here and there. We've got some body guys, engine guys, all kinds of guys. I thank you for the compliment but I just try and answer what I can and leave the rest alone. After all I can't do bodywork for squat so don't expect to see me hangin' out in Body/Exterior.

|5.0Towncar||WATER IN MY TANK. I guess I should go by the directions when it says"Treats 10 gallons". Thanks all.I think I'll go ahead and advance my timing a tiny bit maybe I will lose some roughness. Steve|

That spout connector should be near the dist. in the six wire module harness. 2 yellow wires comes out of the harness (approx 6") and into the 2 pin spout connector that just hangs from the harness.
If you suspect a secondary miss (plugs wires coil), take a spray bottle with an adjustable nozzle, fill it w/ water, and w/ someone putting a load on the engine at about 1000 to 1300 rpm in gear, spray the plug wires, cap, and coil w/ a fine mist. For hard to reach places like plugs in the back, adjust the nozzle to a stream and spray the plugs and plug wire boots. If there is a wire shorting out externally, you will feel, hear, or see the miss. If you have arching at the coil tower replace the coil. Try to do this in a dark place, its easier to see arching. If you dont see or hear arching the secondary its probably ok.
Check inside of cap for carbon tracking.
Recheck plug gap. Set to spec.

|dmorris1200||By the way, what year is your Towncar?|
|01-18-2003 04:41 PM|
|dmorris1200||Unfortunately I don't know exactly for your car without looking it up but usually it's a small rectangular looking grey plug in the wiring harness to the distributor that when you pull it out the computer can't adjust the timing. You have to pull it out, then start the car and set base timing to 10BTDC (I think it's 10), then shut the car back off and plug the connector back in. Now the catch is they put the spout connector in different places in different cars but they almost always looked like a little grey plug. You may need a manual to check on this but if you see a section of wiring harness with a connector hanging and a grey plastic plug in it you found it.|

I last adjusted the timing right when I got the car and redid the ignition.......I was 18 then. I barely knew what 3+3 was.Where abouts is that plug? is it the plug in the side of the distributor that has about 15 wires?

|dmorris1200||Did you unplug the spout connector when you set base timing?|
