Hey all. I'm looking for a little advice/help from all of you Mustang gurus. I noticed today that the engine service light on my dash is on. It's solid and not blinking. I plugged in my DiabloSport Predator and checked the diagnostics to get the error code. It's "P0358 Ignition Coil H Primary/Secondary Circuit". I'm also getting error code "P1000 OBD Systems Readiness Test Not Complete", although I think that is because I'm getting the first error code. Any suggestions? The car seems to be running just fine. Should I just call the dealer in the morning? Should I reset the codes and see if it happens again? Should I check anything under the hood? Thanks in advance for any suggestions.

 

just a question but do you have any type of aftermarket tach driver piggybacking, or a power supply in the fuse box to something aftermarket???

 

Nope, nothing aftermarket other than the Steeda CAI with Predator tune.

 

same problem on mine..........have you do the upgrading for CAI from Diablosport ?? that's it i think....the predator it doesn't read the CAI.
Cole of tech Support can help you. ciao G.

 

You chould check to make sure that the coil pack on cylinder number 8 is plugged in all the way. That is about it really. If you don't have anything connected to it and it is throwing that error, I would just take it in. Depending on how cool or how much of a ***** your dealer is, maybe throw your stock air box back on and restore your factory tune before you do just to assure they aren't going to go out of their way to give you a hard time.

 

Thanks for the suggestions hawgman. I checked and nothing seems loose, so I reset the trouble code with the Predator and I'll wait to see if the light comes back on. If it does, I'll restore back to default factory settings and take it in to the dealer. I found a TSB (04-16-01) that may apply, but I'll wait and see if it happens again first. I drove the car a lot today and there were no problems.
