ok, I recently put a NX 50-150 wet kit in my car and I've only sprayed it twice and the question I have is today while driving the car would hesitate to accelerate and I had no reading on my A/F gauge then my SES light came on, after bout 10 min of driving to the shop my A/F gauge came back on, they scanned it thinking it was an o2 sensor, but it came up with 3 misfire's and the first thing he asked was "did you spray it" everything went fine both times I sprayed is this likely to happen again or what could have caused for my car to act like that????

 

Did you change the plugs when you installed the kit? IF not you need to swap what you have for a set of NGK TR6's.

What shot did you spray? What RPM?

It's possible that you just ruined a couple plugs.

sounds like you sprayed on stock plugs, but i could be wrong. what was the bottle PSI @?

 

Yes, I changed the plugs, the bottle psi was at 800 psi I hadn't installed my bottle heater and when I hit it I was in second gear it's a M6 so I have the window switch set at 3000 and off at 6000, everything went perfectly fine the car has been running fine until earlier today also the only two times I sprayed it was bout 3 days ago....so if it had anything to do with bottle psi I think it would have happened right then right??
