I hope this hasn't been covered before (I'm a newbie here). The Mrs. has a 1990 Miata that has suddenly started to foul-out 2 plugs. Once the car gets over 60 mph it smoothes out but below 60 it jerks terribly which prompted me to change the plugs and discover the problem. Any suggestions??


Thanks in advance.

Further research sez that the valvue cover gasket should be replace since the oil in actually in the wells.

Any other thoughts? NAPA's price is $30.00.

The factory gasket it $21.19 at Finish Line Performance (http://www.finishlineperformance.com/cgi-bin/shopper?preadd=action&key=M1029). They sell some other goodies for your wife's car that you might be interested in.

Thanks. Found one at a local parts house for $17.00.
That and a set of wires made her purr (without leaking).
