try fuel filter and pump

Don't buy cheap gas. My avenger couldent get up hills in penn. untill I topped up with premium. American gas sucks.
Also, did you make sure to buy the parts from the dealer? Aftermarket plugs don't work in Chryslers. Chech the spark output and make sure you have even spark at least 40 000 volts. Fuel pressure may be a problem, but if you have tried these, check to make sure the timing belt hasn't skipped a tooth.
