What's up guys, Im finally back now that I have my car from it being away for 2 years from being built. Hopefully I can make this clear enough without getting myself upset that my NA likes to bog and shutoff whenever it feels like it.
I have a 90 NA w/99 swap and S/C.
Ended up sending my car to a Miata shop to to get my whole motor built, forged internals, supercharger kit,MS2, trans, diff the whole enchilada. The car ran perfectly fine as it should for about 3 weeks (300 miles) and after that it started being bipolar, it began to shut off during idle when warming up, while driving especially when making left turns and when trying to turn it back on it'll backfire and just crank but won't turn over, bogging out while my wideband read low as 10.1 and high as 17.2. These are the issues that I've been dealing with, so I send the car back and was told the CAS took a shit and was replaced, 2 weeks later(50 miles) I'm back to the same issues. My mechanic said it can be 2 things defective fuel pump(Deatschwerks 255) or fuel pump harness female connector that the gaps might be too stretch out which is a common thing for 1.6 models so he says and also since I'm using the skunk2 throttle body its the reason it shuts off since has no idle control valve but other miata's with the same throttle body don't have that issue. Can that really be the problems I'm dealing with here? What are your suggestions/thoughts ??
btw Im running a MS2 and 91 pump
