check high tension lead from coil to distributor and distributor rotor voltige or fuel not reach the pistons,notes2000 rpm you have this stop the car engine on rev 2000 rpm and spray your filter with engine start same time exalaraite to high revs and se the risults.good luck.
do you check the egr valve or the selenoid ........ look with the engine runing pull the trotle cable to rev the engine check the diagram from the egr valve is going to move at all times and the engine is going to missfire ........ then desconect the little hose from the egr selenoid rev the engine 2000 rpm you will see the diference
have you changed your fuel filter in the last year or so, if not. do it. a plugged up fuel filter will cause a lot of issues also. it can cause stalls, hesitation and stumbling.
DO A LITTLE TUNE UP.CHANGE SPARK PLUGS.CHANGE FUEL FILTER.CLEAN FUEL INJECTORS.FILL FUEL TANK UP.AND ADD A BOTTLE OF FUEL INJECTOR CLEANER IN FUEL TANK.WHEN YOU DRIVE CAR AROUND.THE INJECTOR CLEANER WILL CLEAN OUT FUEL INJECTORS.IF CAR STILL RUN ROUGH IN DRIVE.YOU COULD HAVE INTAKE LEAK.
Inadequate fuel pressure, change the fuel filter first, make sure the car sits for at least two hours before replacing the fuel filter because these fuel lines are under high pressure during the time of operation. The pressure usually decreases over time in the lines but wear safety glasses just the same, I would recomend depressurizing the fuel system first, buy a Haynes repair manual for detailed procedure to be safe. If problem persists go to Auto Zone and ask them to check for trouble codes these codes if present may instuct you in detail to replace the MAF sensor or give you a code that must be looked up to find the problem.
