timing adjustment
Hi,
this question does'nt apply to my 96 collector edition, but I thought I would ask anyway. Timing is set correctly and car idles properly, but is low on performance. I advance timing to the point of just a bit of spark knock at WOT and performance is great but idle is very rough. it's a 73 grand prix, 400, with 44,000 miles on it, pertronix electronic ignition. Any suggestions?
