I just got a 94 si. When i go over around 6k i throw a cel. The only problem is that it goes away when i restart the car. I definitly lose power up top once the code is thrown. How can i check for this code? Also any suggestions i am thinking it is part of the vtec solenoid just looking for a clearer answer.

 

have you ever checked the code? it's probably a random misfire as you say it's only happens in high rpm. get a stronger ignition coil if it's really a problem.

im willing to bet its gonna be code 22... if it is take off ur VTEC soleniod and clean the mesh screen its probably clogged up...happened to a GS-R i was working on with a couple of friends..."professional" mechanic over tightened everything and had metal shavings in the oil causing the screen to get clogged

 

it is actually code 8 any suggestions?

 

Replace the distributor. Or at least the housing. Majestic honda sells them for around $100 US.

 

that is what i was going to do and still am i am just wondering why it will only do this in second and third gear but not first?
