1 Answer

We have a 1991 plymouth grand voyager 3.3L recently had motor rebuilt, new spark plugs and wires, fuel filter, throttle positioning sensor, oil change, fuel pressure tested at 50pounds at front of motor, it will not stay running usually in a gear or when you give it gas it acts like it looses fuel pressure usually it will sit there and idle but only at about 1000 RPM and drops back and forth it will however usually IDLE in gear.

HI! Its definitely a MAF (mass air flow) sensor failure. THe MAF has big contribution on engine performance specially on the idling and vacuum supply. It the MAF is faulty the car will hesitate to run and will surely have erratic idling. Once replaced you'll be good. Hope this helps and thank you for using FIxYa!

    Does it stutter when the a/c is on?

    Alrighty, since the a/c does not work theres no need to replace the air idle sensor/actuator. This is used only when the a/c is activated. Go for the MAF and you'll be good.

Engine cranks but will not start. Spark plugs changed, HEI distributorless ignition unit tested good.where do I go from here?


Spray some starting fluid into the intake, and see if it shows signs of life. If it does, then you have a fuel delivery problem.

Now, a 1991... That's fuel injected, yes? Throttle body injection or port injection?

Misfire in 97 voyager,P0300 and P0304,HELP! Need 2 get inspection


I'd have fuel pressure checked, and at the very least, replace fuel filter. Not unusual to get multiple misfire codes due to low fuel pressure, thus starving cylinder(s), and causing the misfire code(s).

1994 Plymouth Grand Voyager 3.8 eng won't start


Check primary voltage at ignition coil and fuel injectors, engine cranking, use a test lite, dark green wire with orange tracer. If no voltage, that comes from asd relay. Some makes and models if the computer doesn't see the cam and crank sensor signals, the computer won't ground the relay.
You need to do some testing.
