What does your wideband say?
Sounds like lack of fuel or spark blowout as far as I can tell. |
O2 clamp?

How much boost you running, kid?
Step 1. Replace your spark plug wires :idea: Step 2. Replace your ECU:loser: your Stock ECU is pulling fuel under boost. Your 2 band-aid injectors aren't going to do shit if the 4 primary injectors aren't fueling the car. Olderguy (above) is too humble to post this link for you: https://www.miataturbo.net/showthrea...light=o2+clamp ^^^get this if you're too cheap to get a decent ECU^^^ Step 3. Next time, don't be such a :noob:, use the damn search button. One vote for Fail Facter based on OP username choice. |
Like my colleagues said, how much boost, what's the AFR when this happens, what's your spark plug gap, why didn't you post an intro, why didn't you search the many threads on this issue, why isn't you location in your profile, why do noobs make me sigh.
Better go put a diaper on and grab a napkin because when hustler and samnavy get up it's going to get ugly. This has been covered over and over. Don't be surprised if you get flamed. 1. Intro 2. Stickies 3. Search(this one's very important) 4. Read 5. Bathe yourself in turbo goodness I'm sure you don't go to some random persons house you have never met before just walk in unannounced and say "hey make me a sandwich", do you? |
