CEL on?_x000D_
_x000D_
How is the clutch pedal free play? Set to OEM specs? Did you try adjusting the clutch cable if it has one?something described as violent like this probably is not in the clutch. the IAC and EGR is probably a good thing to check into. also a look see at the throttle voltage while this is happening would be help full. a scanner with live data would show these 3 things while driving. seems like something is getting the wrong odd signal. maybe a broken wire or something grounding that shouldn’t be from a bad wire.
Hmm, lines near the electrodes…is that similar to carbon fouling as you mentioned when you had the distributor swap video? Good suggestions all around, though.
Quoted From EricTheCarGuy:LEAVE THE SENSORS ALONE! If you don’t have a CEL for a sensor or actuator don’t go looking for a problem there. Remember with performance issues if you don’t have a CEL to start with look to the simple stuff, the plugs, the wires, air filter, vacuum leaks stuff like that. Your methods can actually cause problems while you’re looking for the cause of the problem you’re having which only makes things worse. Besides Hondas RARELY have problems with TPS, MAP, or any of their other sensors for that matter, it’s usually someone that goes in there and cheeses up the connector or wires that causes problems with those items.
To me it sounds like an ignition problem. I’d be checking the plugs (which should be NGK or Nippon Denso), if the wires are OE leave them alone but if they’re aftermarket try this.
umm it was stated in the first post that he replaced the ignition componates with OE. 🙂
here is some other things i would look into http://www.askmehelpdesk.com
Read my post for a similar issue and ideas. Id double check the clutch though to see if it was put in correctly. How are the RPMs acting with the surging?
I’m still trying to figure out my issue but its a really long post so you may get ideas from it.
Eric may protest to this cuz Hondas don’t usually have fuel system issues- which I agree with- but it wouldn’t hurt to

You can’t completely rule out a fuel system issue but I feel it’s at the bottom of the list and I would work on eliminating other possibilities first.
@sjrobinson, when was the last time you dumped in a bottle of fuel injector cleaner and it fixed a problem like this? I’m not trying to be mean it’s just that I don’t think a fuel injecting clean will do much good especially if you just dump something in the tank. When I clean injectors I like to use my set up that ties directly into the fuel system, I’ve seen some pretty good results with it but not with in tank cleaners.Quoted From EricTheCarGuy:_x000D_

As I’ve said many times in this thread Honda fuel systems don’t often have issues it’s usually something else that causes a performance problem, for instance I’ve seen plenty of ignition related issues especially with aftermarket distributors. I think it would be better to take it somewhere to HAVE your injectors cleaned by someone who has a tool set up like mine as I believe that would cost a LOT less than replacing the injectors (especially with aftermarket ones as that would be a step in the wrong direction in my opinion) and be a lot less labor intensive.
I took it to my local mechanic and he spent a little time looking the car over to diagnose our surging problem, (The not so nice surging that seriously moves the car, not just a vibration) and he cleaned out the throttle plates and replaced the distributor cap and rotor. No CE light. Problem still exists. We bled the clutch, removing the air. We are going to have Dodge (our mechanic that is named that by chance) look at it again on Monday. Any update we will post on here, however, keep feeding great ideas, i need all of them =)
Have you gone over the basics? Like–
Ignition leaks:
I know you said you replaced the wires, but it’s free.
Vacuum leaks:
we have checked for ignition leaks but found none, and im going to find some propane for the vaccuum leaks (dont like using carb cleaner because it is too dangerous). Other than that, My brother and I are going to try to replicate it with the mechanic and see what he comes up with.
