To Anyone,
Brought my baby 95 Max to the shop who prev changed the EGR Valve, Solenoid, etc. They hooked it up to the diagnostics machine, chocked the wheels and let car idle while in gear, but nothing. Yup, the mechanics could not "reproduce" this intermittent problem with engine.
I give up. Im at wits end on this. By the way, I had mentioned sometime ago that the headcover gaskets were replaced before this problem with the engine began. To do this, the mechanics had to pull off the intake manifold and such located above the head covers.
Now, I got a question. If the head cover or the intake manifold just by chance had a mounting nut loose by some reason, causing a small leak to begin within the gasket area of the loose nut, could that be creating a problem?
If so, how can I go about ruling this out or finding out if this could be the problem? Someone suggested I spray carb cleaner around the intake manifold mounting area and head cover area while the car was in idle to see if it would make the engine idle roughly. Is this a safe way of seeing if there was a leak in these areas?
Before I undertake another avenue of seek and fix, does anyone have any suggestions? Thanks all
