No the problem is not completely fixed. I have cleaned the EGR tube (what of a job)It was not completely blocked at the inlet end so I'm not sure what effect this would have. I have checked the Purge Valve and that is working properly no crud in it and pulsing OK. I have just this week replaced the MAS with a new BOsch unit. I have checked all vac lines that I can see especially at the SOV, all appears perfect, no cracks no leaks.
The car is running very smoothly with the new MAS with a noticeable increase in power,but idle is still not quite right, it feels like the mixture is weak which does suggest an air leak somewhere. Will check HFM codes after running for a few days and see if any codes return. My next task is to remove the EGR valve and see if it is seating correctly. I can hear it opening and closing when vac is applied but do not know if it is leaking in the closed position at idle.
If any one can think of anything else to check I look forward to hearing your comments.
I have noticed recently that the upshift delay from 2nd to third gear when cold has increased and I now have to drive half a mile before the tranny upshifts or let the engine idle for 5 minutes before driving. I dont think this is connected to the idle problem but who knows? THanks
