The car had sat in Phoenix for 8 months and the distributor had gummed up, so we replaced it. We also replaced the injectors, cap and rotor, O2 sensor, & plugs and wires. We were going to try to replace the one injector and see if that helps. When we first got the car, it smoked all the time. Now, it only smokes when we take off from a stop. We also had to work on the vacuum lines, they were set up incorrectly. We were told when we bought the car that it needed a valve job, but we're not real sure if thats right or not. Could the fuel pressure regulator mess up just one cylinder?
Thanks for your time!
