The engine light comes On in sporadic ocassions, mostly when driving over 50mph for long periods. I took it for scan and the code p32 showed up. I have replaced myself the two EGR valves and most of the hoses. After the replacement of valves the RPM niddle went down from over 2 to under 1 when is in neutral as it was before when the truck was new. The replacement, however, didn't solve the problem with the engine light. I replaced the EGR solenoid and the light didn't come ON for two days, but now has started to come ON and Off as it was before. By the way, the EGR sensor was replaced about a year ago. Practically the whole components of the EGR system are new. What I must do next? How to make the engine light to stop continuing coming ON and Off? It may be a loose connection somewhere?
