LOOK at my DYNO, need help please!
Guys need help here. Look at my dynos, it's so toothy but it should be smooth. Dyno #3 was with C&L meter and I noticed my A/F was too lean 14:1.
So I switched back to stock air meter, changed my old spark plugs to autolite platinum and replaced stock wires with 9mm ford racing. I even took my car to the different dyno shop (I thought dyno itself was wrong). Look at dyno#1 A/F ratio is good now, but the graph is still spooky. What the hell? I know for sure that is something wrong, cause a year ago when I dynoed my car it spun 285 rwhp and the curve was normal I mean smooth.
Anyway, it's '97 cobra. Engine all stock, no chip. The only mods are: magnaflow catted x pipe, borla catback and pullies. The car drives excellent no vibration and no check engine light.
Maybe my stock coil packs worn-out?
Please help me, I'm desperate!
