Limp Mode? Please help

[hamgumball]

I have an h22 swapped accord and when i get on it, the car won't go past 6500. It cuts off hard, worst than what it would if i hit rev limiter. I have no codes, and the car does go into vtec. I'm out of ideas, i dont know where to start. Please help.

Are u using the Prelude P13 ecu? If it cuts out really hard it seems like it's not getting enough fuel or something when it gets into that high range... 6500 sounds like the Accords redline, if ur using the accord ecu still, it's running your engine way too lean for it.

Oh...I just remembered, well this is a issue I had with my accord b4 it was swapped as far as "limp mode goes" I had a tank 75% filled with regular 87 octane gas and just filled the rest with 91 b4 I took it to the shop for the engine swap. My engine ran just fine...but when I got into v-tec territory it sorta ran like crap and the v-tec was so silent like it wasn't even there. After I burned all that fuel and put a fresh full load of 91 octane gas, the limp mode went away. This is the only other thing I can think of if your not pulling any codes.... goodluck hopefully someone can direct u with other ideas

No, running the p13. I've tried the stock one and the chipped one, same problem. Oh and BTW the problem is intermittent. It runs perfect sometimes but most of the time it cuts out.

When do you have problems with it? When you drive with it for a while or what? Check for CEL. You sure everything is hooked up properly and such? Reset the ECU and see what happens.

So the car will not go into vtec if you dont have 91 octane?

It happens a lot of the time. Not just when i drive it for a while. But i make sure the car is warmed up first. No cel's. Knock sensor cel comes on and off. I'm pretty sure everything is hooked up properly. But where should i start checking first, what sensor's miswired that would make the car run like this?

If your KS comes on and off that could be hindering your performance by retarding your timing too much.

No my car went into v-tec but the v-tec wasn't as hard and it didn't feel right. I had like a little over 3/4 tank of low 87 octane mixed with 91 at the time. If you don't run the right fuel (I doubt your doing this) your H22 will go into limp mode.

Here is another msg board with a guy with the similar problems. Read the posts it might help you out..

Well, while i'm driving, i can hear the main relay click on and off and the car will hiccup everytime it does that.

[NAiL05]

The main relay doesnt click does it? You just hear your fuel pump prime.
