You don't get the PRV running by "adjusting" things. If it is not running right then it usually means you have to replace or clean parts. "Ajusting" the O2 sensor (I assume you messed with the mixture screw) only caused you to lose that adjustment. If it won't start than you don't begin by messing with adjustments. Start with finding and fixing vacuum leaks. Next have the fuel injectors cleaned and do a tune-up replacing the spark plugs, ignition wires, cap, rotor, and air filter. NOW you adjust the mixture screw on an engine analyzer. In fact that is the only thing to adjust unless you also messed with the 3 brass screws and the tiny screws on the micro switchs by the throttle spool. Timing generally is "right on" or close enough not to need adjustment. You do have to make sure the mechanical advance and the vacuum advance are working though. If it is smoking a lot pressure test the cooling system to find any leaks and do a compression test on the cylinders to see if it has been overheated. --- In dmcnews@xxxxxxxxxxxxxxx, "painintheass7565" <advantics@xxxx> wrote: > Howdy all.Yup, if you can believe it, VIN 5326 will start but run > ruff after adjusting the O2.
