I think the main difference(s) between this and the current "cranks no start" TSB is that the newer one doesn't include the battery and starter inspection/replacement procedures. However, both involve troubleshooting for starting problems for when you shut down the engine cold - not necessarily for hot-starting issues (at least, I didn't see that symptom listed).

i have a optima yellow top that has about 5 months of use. never had a problem with it. the updated starter has soooo much more kick to get the rotors moving. this was my 3rd starter in about 2 weeks and it is a huge difference. i didn't go to the dealership and have it done under warranty because i didn't want to tear all the crap out of my car. well worth the investment for the peace of mind in knowing that you're much less likely to get stranded with flooding issues.
i would also mention that 'hot starts' were never an issue before i put on the yukon coils, but with the updated starter there is no problem at all. ray, you might want to add this to your list of suggestions... have the updated starter installed before you upgrade the ignition. for whatever reason, it causes a load of problems without it.

ok so I was out datalogging tonight to send them to Jeff and this happened...
Idle...Fine
4200rpm cruise...Fine althought a bit richer than I like it ~13.3 AFR
2nd WOT...Fine until I reached 7k rpms and my car bucked (I think thats a misfire)
What could be the problem here?

my bhr ignition did the same.
I know of a few others that this happened to as well.
I am now using stock coils.
Make your own conclusion though, you don't have to listen to me.

Mine does it to; it could be the tune or a wire - or bad coil. Ray send me a wire for one of mine that is suspect. I'll swap it - double check the tune (it is rich but a 10:1 shouldn't be an issue for these) and get back to everyone.
Remember once you START to misfire it will make your AFR'S LEAN - so if your seeing say 11-12 AFR and misfiring you could still be drowning in fuel (like 8:1).

I didn't think it was possible...but I checked things over and over again....everything was good..new plugs too. Swapped in my oem coils and wires that have ~20K miles on them and misfires are gone. Better performance too...I was losing power in low RPM's and once I got around 6500 RPMs and above...all misfires. Started out at 7-8 PSI. Then got worse and was getting misfires at 5psi. With the stock coils I can run 10 psi no problem right to redline.
Hope you get it sorted out!

if you don't have misfires with those, couldn't you rule out it being a tuning issue?

So I just need to test some more; but been too busy and I was waiting for my wire.
So I'll replace wire, verify plugs are good; verify tune is good and go from there.

Ok I am sure its not running pig rich since I was running mid 10's perfectly and once I hit 7k rpm it was like the car hit a wall suddenly and yes it went lean to about 12.6 I noticed (maybe a little more). The thing is I have triple checked everything, wires are on tight, plugs are new, and of course coils are new. I had a grounding problem at first but that I THINK is sorted out with the new position. I dont know really what else it could be. All my wires look fine so I dont know if one is having problems. And why would the problem only occur at 7k rpms?

Well, it's not as if this is fun for me or that I don't care about the outcomes. Every time a customer of BHR has an issue with ANYTHING they have purchased from me, I take it personally and treat the problem as if it were happening to my own car. This is why I sleep very little, sometimes. Hell, I even take care of people who bought stuff elsewhere in the same fashion.

Again, thanks for taking the time to look into these problems. I will update the thread after I take the car in for the new starter. I'd prefer doing it myself, but I'm not paying $300-400 for a new starter when the car is under warranty. I just hope the dealer will not look at the coils as being the source of the problem.

Well I just got back from going to lunch and the car is misfiring more, the day is HOT as HELL here in Puerto Rico. I am going to switch back to stock coils ASAP so I can test out and see if it is that and if it is I will send it your way charles so you can check and see what it may be.

I installed my kit last weekend. Things were looking good. Until... I tried to start it when it was still hot. After reading the last 3 pages it seems that I am not alone and the consensus looks to be the starter/battery. I have a newer Optima yellow top (last year) so I don't think that is the issue. I too, was having hot start issues before the install and thought it was the old components since I was also getting mis-fire CELs as well. Now there are no CELs but the hot start issue remains. I guess that it is time to change out the starter.
