How it drives. Hesitate to accelerate, bucks, studders
how it started. Dealer said it was an exhaust leak, which eventually turned into a clogged cat
replaced, clogged cat and resonator

i just bought this car back in feb. The car had a cylinder 5 misfire fixed it, the problem was still happening. Brought it to firestone mulitple times, we did coil, spark plug, cam shaft position sensor and camshaft pig tail. Once the car was completely fixed I decided to go to the beach since I hadnt done anything all summer because I was to busy repairing my car. Broke down at the beach brought it to firestone where 3 more codes are now issued p0303, p0868, p0725. I dont know how much I trust this firestone since it is not like my home based one that shows me everything and tries everything just to help me. I need to know if the car is worth fixing or should I get back into a really expensive loan. I need help I work 7days a week and dont have anytime to devote to the car if it is not repairable.

P0303 is a misfiring in cylinder 3. Could be anything from oil in plug tube to a bad cylinder. Spark plugs and ignition ciol are other possibilities.

P0725 is engine speed signal so it could be related to the P0303.

P0868 is secondary pressure down. This is a fault with the transmission and could be a simple fix such as a bad wiring connection or costly which requires the transmisison to be rebuilt.

You need to find out the actual cause and see if it is worth repairing.
