I needed to clear bad EGR codes after replacement so here's what I did:
I removed the negative first and then the + and left it disconnected for about 20-30 minutes. The CEL came on after about 5 minutes of driving and after starting the AC, the CEL went off and did not come back on for about another 20 minutes of driving.
Is that the end of the CEL on this issue?
Are the platinum plugs with about 3,000 miles on them likely to be fouled due to the EGR not operating properly? There is a minor shudder sometimes when accelerating and engaging the cruis control....All in all it runs much better with th new EGR.
Thanks
