Question
My 99 chrysler cirrus 2.5 has a miss that can be felt at all speed (like a small lump on a tire)at sometimes it works perfectly then..when hot it will stumble on take off and almost quit  so far I have spent close to $4000 to fix it. I have given up on the Chrysler dealership's mechanics here is what they have done to find the problem:Remove and clean the gas tank/ filter,new gas pump assembly, replace the 6 injectors new intake gasket new plugs /wires /cap/rotor button  There is no code on the mil light, compression checked ok 3 days later The dealer said is was fixed.....but no guaranty
at last resort the mechanic down the road tried a used distributor
and used computer ..it all worked with no changed in performance
the car is in super shape otherwise.. HELP please before I loose my cool and take it to the junk yard
