Engine stumbles at 3000 rpm

[bkcorso]

mouchyn, thanks , I should have mentioned that to him.

Update, so far I have replaced the following with no change,

plugs,cap,rotor,wires & filters
throttlebody w/tps & fast idle valve
dizzy
both 02 sensors
ecu
vaccum control box (map sensor)
ignition coil and resistor
The resistor on the drivers side fender (metal box)

I've tested the following,
tps, and tw sensor, both in spec

I'm running out of options, what would be the best way to isolate if fuel or fire is being cut ?
I will also test voltage from the alt, back to basics.

Can you see what's wrong?


Gotta love it !!!




I was wanting a hand grenade at this point, but I kept on it. I figured it had to be electrical,( I posted this thought earlier ) only because it was so random with the symptoms, and the cel light flickering, and not giving a code. With the engine running I started tapping all the sensors..no change, then went around and lightly tugged and pushed on the connections, then the harness.

That is when I hit gold, tugging on the big bundle of wires that comes of the drivers side fire wall caused it to stall. I had never stalled before. Then went to the injector harness, (I went there because I had earlier put a screwdriver on them to listen, and when the engine would stumble, they sounded like they would flutter) it stall again, I looked around and saw a spark, and that was the ground wire sparking on the manifold. I had meant to look for loose wires the night before, but was pretty wore out.( No light makes it easy to spot a ground issue, or a spark plug wire arcing )

3days of getting intimate with my Honda....Priceless

I gotta give big thanks to all that help, it kept me focused on tracking down the culprit, and not giving up. Turns out It was me !!! Good news is that now I know where just about every part is under the hood, now I just have to figure out where the valve cover is ??? jk

well, at least you got all that nice new stuff replaced in.

you know what's funny? I just had the same problem with that ground wire bundle.

when i swapped in my freshly rebuilt engine, i couldn't get it to start. The ECU wouldn't even come on. I tested and replaced damn near everything. I was testing wires at the ecu and found the ground wires had continuity to each other, but not to ground.

I looked and looked and looked and couldn't find anything wrong. I finally gave up and grounded those wires myself and the car started right up. Two minutes after getting the car started, i noticed that same bundle wasn't bolted down. i bolted it down, removed my ghetto wire-tapped grounding at the ECU and everything worked fine.

it's always the simple stuff, huh?

glad you found it.

Great, Now I have no money to put gas in it !!jk


mouchyn, I had a feeling it would be something simple. I also got a crash course on how my Honda doesn't work !!! Thanks again. I've only got one more issue, then it's road worthy. It will be worth it

quick question, if your engine idles at like 2500 rpms and you pull back on the gas pedal is it suppuse to drop it? if not can someone please tell me wats goin on wit my f'n car?

loosen your throttle cable slightly its to0 tight. Lube the linkage and the shaft.
