Intermittant Acceleration problem 94 Club Wagon
I have a 94 Clubwagon and have recently replaced the fuel pump and fuel filter. Ran great, for a while, and then started having issues where it randomly wouldn't accelerate correctly. To manipulate it to drive you would need to push the gas pedal and let off, when you let off it would get the gas, when you pushed on it, it would cut out. Idle runs rougher as well.
Originally thought fuel gauge was bad, and had low fuel, as it would run better after putting in gas, worse as that gas ran out.
Has nearly a half tank now, drove it for over a week, never letting it get lower than 3/8 tank, 30+ miles or more at a time, nothing wrong.
Drove it 6 blocks, started up again.
Codes are reading EGR valve fault, and now throttle position sensor above maximum voltage.
Any ideas if it could be the sensor, or maybe a vacuum leak? Bad fuel pump?
