Hello everyone! First time user, desperate times... any way I have a real good question for some one that's smarter than me! Driving along the other day I noticed a slight miss I one of the cylinders, stopped at a signal light and when green hit I started to go then suddenly down to a sputter she went, trying to stay running I slowly was able to gain some speed to finish my travel to work.
At the end of the night I chanced the ride home. At sloww speed she sputtered but when getting to highway speed around 70 mph she ran good until exiting. Now I`ve had it to a chrysler shop and paid 85 bucks to no answer (they where wrong) I`ve changed plugs,wire`s,rotor, rotor cap, etc . Now my fuel pressure is 49lbs psi. and she won`t even start now.

I`m getting a spark on the plugs and I`ve even shot fuel up the intake and still she won`t run at all... is the spark not hot enough under the fuel pressure? Oh, timing is also good.

Hoping some has an answer. Thanks:confused: bugz

Try changing the fuel filter as it sounds like you are not getting enough fuel to properly power the car. Sometimes the simplest thing can make a huge difference.

Based on your symptoms, the problem may be the catalytic converter beginning to become clogged, but I'd have to see how much spark you're actually getting before I give the ignition coil a passing grade. You may have spark when testing outside the engine, but once you introduce compression and a fuel charge, your coil may not have the umph to fire the plug. You need to find someone in your area to do a proper diagnosis.

What did the Chrysler shop improperly diagnose? You say you spent $85 but they were wrong. Rich is right; if you went too long without doing a tune up, you very well may have damaged your converter.
