Trying to identify injectors/ MOSFET failure
After finally tuning my car with MHD last night went with a stage 2 93 tune, I went out and did a few test pulls and started having some misfires in higher RPM, I'm changing the spark plugs in the next few days and knew the ones that are in it are just factory replacements but I just wanted to get a short test drive in.
Decided to test out MHD launch control as mine is a 6 speed car, LC set at 3000rpm gave it one pull threw 1-2 with no misfires until after I had already let out of it. Long story short. 30BA code, blew a MOSFET, will be trying to have them replaced with upgraded ones for a temporary fix until I just go to a MSD81. Now I'm going to replace coils and plugs while I'm at it to hopefully not have any more problems for now but I was also curious as to which injectors are in it so I know in the future if that's something I'm going to have to be concerned with but I don't see any identifying numbers on them. Anyone have any idea? |

I'm curious how you determined they're index 1's.

Not necessarily. Have a look here. Index 1 actually seem somewhat reliable.

Index 1's are fairly reliable up to say 150,000 miles. |

As you indicated in post 12, index number is on the first line.
The bottom set of numbers are identical in the photo i posted, which is index 1 and what the op posted. How is it index 10 then?

The OP should: 1) get the New Updated MOSFETs put in. 2) install Eldor Coils 3) install new plugs (OEM or NKG one step colder gapped at .022) 4) if he still has issues then, and only then get index 12 injectors. I do think with reman injectors that the OP is on borrowed time. There is a way in INPA to check flow levels so one can check to see if the injectors are working correctly. |

Dude, just a little attention to detail goes a long way...
Nope. Quote:
Nope. Yes, we're aware of where the index number normally is. Quote:
