that seemed to be the topic to me . your car runs fine, but the vac drops a little here and there and your rpms go down to 700rpms (which is factory idle on fc's...not sure on fd's but i dont think many cars have a 1k stock idle). basically start going over the other 2 factors in the equation (theres spark, fuel and compression....your compression test sounds iffy sinc eit idles fine but you only ready 30psi) check everything out ignition wise since its obvious youre getting fuel since youre fouling plugs.



we should rename this topic "fouling plugs like nobodys business"

im getting my commander today ,



is there anything I can look for on that? Will it tell me if the ignition is fuked up some how?

 

get a multimeter and do measurements. gotta get dirty to figure this one out.



unless you wanna be like a dealership and just blame the most expensive thing and replace, then find out "oh look it was actually just the $20 part"
