Q: My check engine light flashes on idle sometimes, recently changed the oil pressure sensor and now the light flashes very rapidly
My truck has the check engine light flash fast whenever im not accelerating my truck. It use to be occasional when it happened but it started happening more frequently. My uncles believed it was either the oil pressure or the oil pressure sensor. I bought and changed the oil pressure sensor and now the check engine light flashes very rapidly everytime the truck idles. What could be the problem?
