I don't know whats up with my car. I have 99 Si with Vortech Super Charger in it, and just yesterday I installed my MSD ignition system. My car started up and drove around fine after the install, except when I hit boost, my car starts to stutter, but thats another problem.

major problem is I'm driving to work this morning (freeway) and I notice random sputs of loss of power (very short term but noticable). It wasn't till I was in a tunnel (half mile tunnel) that my car went crappy (bad place to be stuck). I luckly putted my car out but a CEL code came up. CODE 54.

its suppose to be the crank fluctuation sensor. What exactly is that (or causes that CEL)? And better question, is it safe to drive my car home (40 miles away). Or should I get it towed?

 

The CKF sensor is located on your oil pump as seen here:




See if it became unplugged some how. Other than that I duno what to tell you or why you're throwing that code, but for some reason i have a feeling its due to your MSD unit.

 

Sorry to steal your thread but I have the same problem.

MSD SCI
SS BLASTER COIL
NEW ACURA DISTR.
NEW SPARK PLUG & WIRE
NEW CAP & ROTOR

I have a 96 ITR Motor and when it's trying to pass 4500 RPM it starts to Rev. up slowly and the RPM jumps.

Do you think it's my MSD? it's the only item I have not change yet?
