try putting some extra grounds sometimes that helps

This is when the 2ndary injectors are coming on, it could be a sign of a dirty or bad injector.



I had 2 of them in my motor. At 4000 RPM it simply cut out. I tried the ground trick and that didn't fix it. Changing the 2nd injectors did!

i feel it slightly. i know my injectors are leaky, but it still runs hard so i dont bother. I also noticed the the connector on top of the injectors is cracked. One time my car just wouldnt pass 4k. wiggled the injectors a bit and it fixed it.

there are sooooooooo many ideas on the 38k prob.( mazduh )published a tsb on this stating that this was due to a faulty ground to the ECU. i have done most of them and the only one that seemed to help some was grounding the two crimped connections from the ECU. there are rather extensive write-ups on this on the RX7 forum just hit the search button and type 3800 hesitation you will be reading for an hour or two. good luck and be sure to buy some VISINE before you start.
