Hey Skools, I use the mercruiser cap and rotor, been getting the mallory or sierra, they have the good brass terminals. If you get far enough along, I have a bosch intake/injector set up off of a mpi motor, its supposedly a good swap, I've talked to ferm about it, I ended up with a spare one. Don't know if you're able to get it pass emissions check(no egr). Takes some tuning and wiring, Let Ferm tell you about it.

what about the cap i posted from ebay guys whatya think worth a try or not. and really the only thing that hasn't been changed is the spider it has had intake gaskets replaced which not long after maybe 15k miles later this misfire issue started. honestly it has no power like it use to plus fuel milage has gone down somewhat from it use to get. it mostly started when this crappy fuel came out. i can run sta-bil green marine and it will run good but then it comes back. my dads 96 Z71 seems to have twice the pep my 99 Tahoe has. plus it has an Accel Super Coil which has been on since the factory crapped out 40k miles ago and it has one hot spark

it sounds like the spider injectors to me more than the rotor and cap. What you are describing it sounds like the way my blazer used to run before I have to have the injectors changed in it.

Can't tell from the ebay pics, but you want the blue colored cap which is the marine version. I've had problems with the black ones on more than a few.
