I have reoccuring issues with my chevy K1500 5.7 liter ext. cab/ service engine light comes on randomly and causes hard shifting and power loss while running also blinkers, and brakelights dont work?
I have issues with my truck but only when it wants to... it starts great runs like a champ until, my service engine light comes on at random... now my truck looses power wont go over 2500 rpms, and can barley make it to 60 mph on the freeways, it shifts hard with a slight delay and clunk while driving, and shifting through the gears sitting still. If I get to a red light and turn my key off and shut truck down, ill wait and turn my truck back on by the time the light turns green the service engine light turns off and my truck runs just fine no problems. my truck has lost all power and bogged down once trying to accelerate from center lane into traffic and I had to crawl out to get to 10 mph before it got power back. these things only happen when the service engine light comes on at random. also, my windshield wipers work randomly at will and will keep going after I turn them off, they'll stop in the middle of my windshield at random or if I wiggle the switch, or shake my steering wheel. running lights work with head lights but my brake lights on my bed don't light up with brake pedal, only the light on cab does, nether blinker works in back and the front right blinker doesn't work anymore either. we've replaced all the bulbs, no effect. my brake lights and blinkers have gone out one by one, on and off over time and now they don't work at all anymore. my engine has over 200,000 miles on it but my transmission has been serviced last year and guarantied for 100,000 more miles. I have an engine leak that causes me to put about quart a month or so into it. I cant figure out what is going on with my truck, but its getting dangerous. the issues are so random, and so odd, I just say it haunted. there's almost a new problem every day. subwoofer has gone ballistic when I hit brake pedal. 2ce only. stereo has fluxuated volume, power steering has come on and off, and a few times my brakes get over sensitive and feels like its trying to activate ABS upon the first depression of the brake pedal after starting cold. only every once in a while. there are two amplifiers and a subwoofer in my truck along with a bored out high intake system with a cleanable cannon filter, anyone please help give me an idea how to approach this. my truck is completely unpredictable!
