So last November I bought an MSD pro billet distributor for my '90 lx without doing any homework and as you all know that was a BIG MISTAKE!!! So fast forward to 9 months later I'm recently tracing down a RPM sputter around 2500-3000 rpm. So now that I've done a lot of fuel testing and it has no fuel psi loss or drop, new fuel filter etc. I've concluded that this is probably my problematic part after reading tons of MSD problems in recent years. I don't have any spare parts to throw on it and check the TFI or a stock dizzy to test, but as of right now I still have 3 months left on my warranty at Summit Racing. So with my receipt in hand with invoice number etc, I call the guy in customer service and explain to him my problem and how I cannot rev it over 2500 rpms before it skips. It starts fine, idles fine, purrs like a kitten etc , ...I even swapped out my TPS last night cause I was like, maybe it's a voltage % issue with the pedal pressing down. NOPE still there. TPS was really old and giving a a high idle a few times so it needed to be replaced. I even moved the TPS wires once when it started to idle high and it dropped back down after wiggling it, so I'm not out any money, that was coming anyways. So he says "Bring the MSD in and we'll swap it out. Then he says, "Nope looks like they're ALL on back order for weeks from people sending them back and they have none left in the warehouse!!!" So by this time I'm pretty confident this is in fact my problem. Then he says "Well, we do have the Summit pro billet etc, you can bring it in and swap it out for that one and we'll refund you the difference." He even authorized a code for me to show them when I arrived to enforce this swap under warranty. (we will revisit this customer service but so far so good for Summit!!) So regardless of this actually being my problem(99% sure though) or a FUTURE problem soon to be, I believe this is my way out of this MSD problematic arena!! Only question is, should I tell them I want another brand or take the Summit (Part Number: SUM-850411) ?? I was thinking of using the $$$ difference to snag up a motorcraft/delphi ignition module and save the distributor one for a back up. Darn MSD was $270 so I gotta have a little wiggle room. I will have to use whatever brands they carry for the swap. http://www.summitracing.com/search/...t/ignitions-electrical/part-type/distributors HELP tell me your thoughts on these distributors, please advice my warranty!!!!!
