Well, you know that you need to replace the cam cover gasket, along with the plugs & wires you've just replaced, because oil is getting down into plug hole # 3 and will eventually ruin that new plug wire. Do you have an A/F ratio gauge in the car? Is it working? You may have suddenly gone too rich. In a message dated 3/22/2010 9:52:22 P.M. Eastern Daylight Time, [email protected] writes:
I checked the oil for signs of coolant and the cooling system for signs of oil. Both systems appear to not be mixing. Changed spark plugs and plug wires. O2 is 114 on the LINK with engine idling. Cruising in 4th gear at 3K RPM yields normal O2 readings of 78. The MAP is showing around 55-60 kpa while idling which is much higher than the usual 29 kpa. I pulled the new plugs after letting the engine idle for about 5 minutes. Cylinder 3 plug was wet with oil. The other plugs were black and dry. Performed a few tests with the engine running; Pulled each injector plug and these were the results- Cyl 1 = RPM drops Cyl 2 = RPM drops Cyl 3 = RPM drops only a little Cyl 4 = RPM drops moderately Next I pulled the Plug wires individually while letting the engine idle- Cyl 1 = RPM drops Cyl 2 = RPM drops Cyl 3 = RPM drops only slightly Cyl 4 = RPM drops This is an engine built by The Dealer Alternative about 80K miles ago. It has an FM3 Turbo Kit. Please help!

The last two cylinders could be just pumping charge between the two. _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
