Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
TPS and Mass air flow sensor replaced and tuned up replaced plugs & wires changed fuel pump and filter and 2 coil packs , and when I remove the connectors to the spark plugs on the right side of engine and it still runs the same? The engine light stays on then when u drive it starts to flash and it runs better when your on the freeway and when you come to a stop it wants to die the rpms are at 400
how do I get the codes with a OBD reader I don't own one .
