My 04 GX has had a "Stumble" problem primarily at light load throttle - which generally goes away after warm up - or at rpm > 2500. My dealer has been using the data logger and working with Honda tech. Noticed it originally at say 40-50 k on it (bot it with 30k) - and now at about 97 k it seems to be getting worse. For a long time I thouht it was a tranmission slip - felt like a sprocket slip) - but now it clearly is an engine miss - which increases in severity at high altitude - over 6000 ft (Lake Tahoe, Sonora pass, Tioga Pass, Glacier point). Cylinder head replaced due to cylinder leakage out of spec, plus I think they have replaced injectors, pressure regulator - tried swapping ECM with known good one. Seems like some type of vacuum issue or some possibly a sensor - still a work in progress .... found interesting info on the honda cng control system in http://www.socalgas.com/documents/bu...on%20Study.pdf at pages 11-12.

Re: 04 gx With Stumble
The only way to really find a bad coil causing this problem is to replace it. One at a time is easy with coils. As for longevity, I think one of my GXs with 130k still has the original coil packs. It's a crapshoot how long they last.02 GX

Re: 04 gx With Stumble
I've had the same symptoms/symptoms on my '04, swearing it was he trans slipping, worse when it was cold and at low rpm. I had my shop ready to order a trans and my top tech, Jesse, said it was coils. I was at 95k mi at the time. He replaced all 4 and it ran perfectly afterwards. It's the only problems I've ever had with it. The good news is that if you're in Ca., it's covered under warranty to 150k.

Re: 04 gx With Stumble
So how much are the coils if they are not under warranty?
My '04 Civic with 49k miles seems to have this same problem, though I think the tranny might be bad too ... when cold the transmission will stay in neutral (even though the shifter is in drive) until given a fair amount of gas, at which point it lurches forward. Similar problem when stopping; the transmission will go in and out of gear, making stops anything but smooth.
