Question about Cars & Trucks
When I drive my jeep with trouble because no acceleration when I hold down gas pedal and I think there is a parachute behind it
Well, code 51 means the O2 sensor is telling the computer the fuel mixture is lean. So the computer tries to make the mixture rich by opening the injectors longer. I doubt the sensor has failed, but rather your fuel pressure is low.
If the sensor has failed and pressure is normal, you should have black smoke coming out the exhaust pipe.

Right rear?...Code 51 signifies a lean running condition from an abnormally rich correction factor. That means the computer tried to correct lean running by increasing injector on-time duration to max, but still can\'t keep up with lean condition. Likely it\'s not the sensor, but a vacuum leak letting your intake suck in extra air. Check your vacuum hoses for leaks or breaks, check the big air boot going into intake for loose fit or tears, punctures, and check your intake mounting for leaks-maybe your intake manifold gasket has failed.

TRY CHECKING THE WIRE CONNECTORS ON THE PCM WHICH IS LOCATED ON THE PASSENGER SIDE FIREWALL. IT HAS THREE LARGE MULTI-WIRE CONNECTORS HELD IN PLACE BY THREE BOLTS. WIGGLE THE CONNECTORS WHILE TIGHTENING THE BOLTS CAREFULLY SO AS NOT TO BREAK THE FRAGILE PLASTIC ENDS. HOPE THIS SOLVES THE PROBLEM. KEEP ME POSTED PLEASE. THANKS FOR USING FIX-YA. GOOD LUCK

has your brake pedal seem to be stiffer than usual? the sound you hear is from the brake booster if it has a leak it will cause a noise but you would have a stiffer pedal because the booster is loosing vacuum.

I just had this problem and replaced the camshaft sensor, crankshaft sensor, and coolant temp sensor. i replaced these items because of high mileage. try these but first check your relays located under the hood on the passenger side. sometimes they get hot and fail.

Sounds like a vacuum problem.Listen for hiss noise under hood and under dash. may have a bad vacuum diaphram that controls blend door or leaking vacuum line.
