I just had this issue when I went to 460cc injectors and found that my warm up enrichment was making it shut down/stumble after 185 degrees. I bumped the numbers around a bit until it would maintain decent idle and it's been pretty good since. I still have some very rich hot start conditions that I am working on but it's all part of the MS game.

Here is the msq. It is something Scott made me which was a mix of a 99 and a 94 basemap with some VVT thrown in. I have touched just about nothing in it yet. I have started the car on it and was letting it warm up. Hell I don't even think I have VVT enabled on it yet.

So tonight I got some time to work on the car before it got dark and started raining. The first thing I did was try to start the car and took a video for you guys.
Something timing wise sounded off. I then decided to check for spark. Pulled out a wire and tried to start the car, got nothing. Swapped to a spare coil pack and same result. So I decided to pull off the valve cover to make sure the timing belt was in place, and timing was set correctly. First thing I noticed was oil on the intake cam gear. I figured one of the 10mm bolts was loose. Here is what the cam lobes looked like with the motor at TDC.

Intake cam gear is a good bit off.I then pulled off the cover to the 17mm bolt that hold the cam gear on. Lots of oil comes out and I find the bolt is loose. So at this point I figured out what happened. I put this motor together about 2.5 years ago. It was in my other 94 for about 6 months and I put about 1000 miles on it. I then pulled it and it has sat in my garage for about 1.5 years. I never checked that bolt when I dropped it in this car. So I remove the bolt and then gear and take a look at the back.

Yep cam gear is fucked. Luckily I have a spare just in case something like this happens. I had let concealer404 borrow it about a year back to test on a car he was working on. I go and dig it out of the box from when he sent it back. I put it on the car and notice something that seems out of the ordinary.
Never seen that before. I pull it off and I can move the inside.
Concealer is mailing me out another one. Hopefully it works and I can get the car back together. I will be making sure that 17mm bolt is torqued to spec.

FYI, if you manage to strip out the torx VVT actuator cover screws (like I did), it's just an M5 .8 10mm screw. I found allen replacements at my local hardware for about 1/4 the price of Mazda screws.
Why does everything torx seem to be made of case-hardened cheddar cheese?

I installed Tokico Illumina shocks with FM springs today. My red seats are currently getting new leather covers installed along with seat warmers. Hoping to get those back from my friend on Sunday. Now I just need to swap in a NB throttle cable and install some hood pins and this car. Then time to start tuning it and driving it.
