I have a 95 chevy blazer 4.3 vortec v6. The engine check light is on. Abs light comes on after 10 or 15 mph is reached. Abs started after changing brake pads. brake cylander seemed a little hard to compress back in to fit pads over rotor and had to release bleed valve to get pads over rotor with a c-clamp on driver side. 2nd problem check engine light has been on for months. Did not pass emissions first time untill replacement of O2 directly in front of cat converter. Then replaced exhaust pipe and cat converter. Check engine light still on. one week ago engine started chugging when foot not on pedal, stop light/siign/idle. Changed plugs, wires, cap, rotor, feul filter, and throttle position sensor, and feul pump is only a year old. Funny though. does not chug when throttle position sensor is disconected. just runs at high idle and thunks into gear, but no thunk into gear when tps is plugged in. 3rd problem, I cannot get any code reader to read code. I've tried 3 differet obd 2 code readers and get "unable to establish link" "shucks" and "harbor freight" obd 2 reader and code read error "MAC' obd 2. Fuses are all good. noticed also coolant levels drop sporadically. estimated 1 gallon every three- four weeks.
