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?

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.
