There was actually a recall for this. Go to your local GM dealer and have them check your VIN for a recall. If not under recall get out of there its easy to repair yourself don't let'em fool you. Remove the front pads caliper and rotors. Locate the abs sensor mounted to the wheel bearing assembly by a small socket head cap screw (Allen wrench). Remove the bolt and softly gently/wiggle the abs sensor around until it pops up out of the hole. some will break, which is why it would be nice if the recall applies to your vehicle that way if they break gm replaces. Once you get both sides removed, clean the mounting surface of all rust or build up with w-d 40 and small steel toothbrush then wipe off excess with clean rag and mild soap and warm water, dry completely make sure no spray residue exist on parts, Next apply a thin layer of lubricant grease to prevent future rusting and reassemble. The rust build up under the sensor is causing the angle to change resulting in inaccurate wheel speed readings in the abs module your abs module will interprets this as a wheel is either slipping or skidding and applies your abs. This should make you happy with no more irritations. Good luck with this.

Hello. It seems either your water temperature sender is malfunctioning or your ignition module is overheating.

ABS seems to kick back on brake peddle at slow speeds


low speed activation of abs[will not set off code ] can also do brake studder without touching brake usually does it under 5 mph the problem is one of the sensors is dirty or has some corrosion on it ===chevy back in 2000 did a partial recall on the tahoe for the same problem the fix was to remove the sensor and clean it if the corrosion was to bad than sensor was replaced === the problem with no code is u dont know which sensor is causing problem u would need to remove both and check them

My 97 Legacy started to studder when stepping on the gas from a dead stop. It does not seem to studder at higher speeds. Do you thing the Fuel filter may need to be changed?

96 Ford Explorer is studdering (misfiring) when going up hills


I have the same exact problem that just started immediately AFTER I got a tranny service where they changed the Trans Fluid, Trans Filter, Fuel Filter. Took it back and they say nothing is wrong with it. Took it to the dealer thinking I could get some REAL answers... they just told me to replace spark plugs, wiring & coil, for $900. Only studders when quickly accelerating above 40mph. I've check other forums, they say to clean the Mass Air Flow sensor. Haven't tried it yet. This seems the easiest before replacing spark plugs. Any other suggestions anyone?? Please.....

My jeep studders like it is starving for fuel


It could possibly be your TPS or throttle position sensor. It plugs into the side of the throttle body and tells the injectors how much fuel to squirt. If the voltage source to the sensor is incorrect it may cause the jeep to idle rough.

2000 buick regal, abs studdering noise.


If you are braking hard and one or more wheels lose grip, the ABS system will modulate brake pressure in pulses to the slipping wheels. That is a normal feeling when this is happening. If you have a pulsation under light braking, it is likely that you have brake rotors that are no longer true and and need to be replaced or machined.

Rear right brake locks and studders


Get your caliber replaced and if it still has the factory rotor also get that replaced. Recommended to get both replaced at the same time.

Engine bogs and studders in low rpms usualy when warm


this maybe a fuel problem check fuel filter. also clean maf sensor, (manifold air flow). YOU CAN GO TO ANY AUTO PARTS STORE AND BUY A CAN OF MAF SENSOR SPRAY. FOLLOW DIRECTIONS ON CAN CAREFULLY. as long as you have the spray clean iat sensor, (Intake air temperature) it is in big hose from air filter to throttle body. it just pulls out from hose. it would not hurt to make sure the plugs are ok. because these two sensors have a lot to do with the load on engine as well as the map sensor.
