Rough idle

[glowstang93]

Last fall, I had the timing belt changed at around 70,000 miles. It may be coincidence, but after that, when the car is at idle in park, it vibrates more than it used to. I'm going to take it back to the same shop next wednesday to have them check it out, but could it be something they did wrong when they changed the belt? Thanks in advance for any help you all can provide.

Probably is their fault...learn to work on your own stuff or expect this to happen frequently.

And lose those bosch platinum +2 plugs. 2.3's run like ***** on anything other than motorcraft.

Just a little advice from me to you.

This morning I got this wild idea to go ahead and change the plugs and see what happens. The first plug wire I pulled off, was not even connected. The connector was on the plug and the boot was in my hand No wonder it was running rough. The only thing I can figure is with the dual plugs it was less noticable as a miss in the engine. Now the idle is steady and take-off is clean. Yes, I got rid of the crappy platinum plugs and put in good old Auto-Lite Plugs Man those platinum plugs were so ugly when i took them out I also made sure the plug wires had plenty of dielectic grease in them. Yipee, cars running good again and I saved a ton by not taking it to the shop

I had the same problem, but mine was worse when driving. I felt like a bobblehead Toy on someones dash. it was bad. turns out it was 2 of my wires like that. Replaced wires and plugs, now when it's cold it wants to die when it idles or drops rpms because of shifting. other than that it runs allright. Gotta replace cap rotor and tfi that SHOULD take care of it im hoping

If it seems like your car wants to die when you take your foor off the throttle and depress the clutch when you're shifting then perhaps your TPS is slightly out of range. Stinger has that listed as one of the symptoms of an improperly adjusted TPS.

Just my two cents

Here is a link for you to what I was talking about
