Actually i read some of the pr

Actually i read some of the previous posts and did some probing around. i found that the coil wire for cylinders 5-8 broke in half just before it plugs into the coil pack. so only half the engine was running. I have a ohm-volt meter does anyone know the correct resistance the spark plug wires and coil wire should be? also when i check the resistance should i measure from wire end to wire end or wire end to inside of dist. cap? Thanks for your time.

Corey, I'm not certain abo

Corey, I'm not certain about the 308 QV but the Microplex ignition in the 328 is very sensitive to ignition wire resistance. I rebuilt a set with NAPA 7mm innard wire, brass terminals, etc...and car would not run after all my trouble. Jeff rebuild a set for a TR successfully though.
Since you'll really want to replace all the wires anyway, there's usually someone on Ebay selling the complete set for $250-300. This will be the easiest (and possibly) most reliable manner of repair. Use your multimeter to ensure good continuity after installing in distributor cap. Never a bad idea to replace the plug extenders also (about $75/set) while you're there.

I say that because if you had

I say that because if you had "other issues" the least they could have done was mention it to you & at a minimum run an Exhaust Gas Test after their work w/results to insure the engine was running correctly. I can understand a Jiffy Lube doing minalmist work, but not a dealer.
