So Im completely stumped

I have a boosted 94 integra ls. Completely stock b18b1 motor.

The problem: My tach goes completely crazy when I give it WOT and I gets into the higher rpms. Whenever the tach shoots everywhere, it feels as though it misfires and looses a good bit of power.


It did this on a completely stock ignition set-up with nkg wires and bkr7e plugs. I figured that it obviously had to be something within the dizzy, so I replaced the entire distibutor with one I had off of my old ls. This dizzy had the full msd set-up ( sci box, blaster coil). I installed the entire set-up and dizzy (which gave me ZERO problems before) only to discover that I still had the same problem. So after a few days of running it like this, I returned it back to stock, hoping that the problem would be easier to diagnose without all of the msd.


I found a few people on here who posted up similar problems. They all found the solution in replacing or completely bypassing the ignition control modual via a circut board. So today, I removed my ICM and headed off to advance to get it tested. Low and behold, it failed the test. So I bough a new one thinking the problem was fixed. I installed it only to find out that the problem is STILL there.


The coil is nearly new. The cap and rotor are also practically new.

Could a cam or crank sensor possibly cause it?



Any help would be highly appreciated

 

How are the connections to the ICM, are they tight?94

 

I put them on nice and tight. Ill look over all of the wires again though to see if one of them is possibly damaged.

 

This is JKOBD from IA. Once you get your friends distributor that will probably solve the problems. Especially since it reacted so much to being hot.

 

Yeah Im hoping so.

Figured I post up on here too just to hear some different opinions.

Thanks for the input bro.
