I have tried to search google and forums and got no info on it so hoping somone can help. So I just did a 95 1.8L swap in a 93, and the car runs great. I have about 650 miles on the rebuild but I just noticed a glitch in the rpms. I,m stumped because the engine doesn't rev with it, it sustains the same rpm but my needle will spike a bit. In other words engine will stay at 3k rpm and my needle will move to 35k or 4k. Any ideas, mechanical or electrical? please help thanks!

 

this can be signs that your ignitor is on its way out.
