Cylinders 1, 3 and 5 have multiple misfires according to advanced discount auto parts little hand held engine code reader. It idles erratically, if I get on the gas hard it wont go anywhere, it will shudder later on around 45-65 mph, and the engine makes a 'puff' or 'whoosh' type sound when I have it in park listening to it. The mechanic in my area doesn't know how to fix it only that it's electrical and he's stumped. I need serious help people! Please! Any suggestions or help would be greatly appreciated! I took it to this mechanic a little bit ago for the same problem. He gave it a serious tune up. Spark plugs, distributor cap, spark plug wires, filters... the works! He also replaced the downpipe because it was rusted to the cat converter because it got clogged when it was messing up. It ran fine for a day or two and then slowly went back to the same problem. He is charging me for both visits of course even tho his work was only a temp fix. I know it's not all by the book and easy when you're a mechanic but I have limited funds also.

so i replaced it and shes drove like a champ ever since. If that doesnt help, get ur injectors checked out, if they are clogged then that could be whats causing it also.

trying to diagnose this... and the tech had 22 years working drivability with late model Chryslers.
while the engine is first started and still cold and in "closed loop", or running on its preprogrammed settings until warm... approx 10 mins), it does not read signals from the engine sensors. Thus its runs "ok" at first, with a slight bog under throttle and funny whooshing sound, back fires too... and gets worse... almost like your cat converter has clogged completely. As it warms, switches to "open loop", reading sensor info which is improper due to the crank and cams out of sync.
