It's been a week I'm experiencing an unusual behaviour from the engine. During hard acceleration (usually merging into hwy traffic), there is a momentary fuel/ignition cut like symptom. More like a hick-up and then back to normal. First time, I thought I had little fuel left maybe caused it. But it happened again after refuelling. I happens at 4-5K rpm. I have BOS slip-ons. I don't know if it is related. I also, few weeks ago, checked the air filter, it was clean so put it back. I mostly use 87 octane gas. I know it is guess work with this info but any thoughts?

If it isn't very consistent, maybe you have something in your fuel filter/fuel line. With FI though, it could be something as difficult to find as a frayed/shorting wire. Sorry, very little help I know.

How old are the plugs, Ruhi?

I had about 7k on mine, and had a stumble off idle that didn't go away with mapping. I replaced the plugs last night, and the stumble is totally gone.

Might be worth a try.

Maybe its the joke, re-formulated "cleaner burning" :roll: enthanol based farmer subsidizing EPA mandated fuel?

Oops... I didn't realize I was in the garage... Back to the pub before Maxx kicks my ass...

I will check the plugs but I woud suspect bad plugs would effect the overall power rather than resulting intermittent hickups. (?)



It's OK we are in the in the "garage" section. It's all about learning. Having said that; it's not "farmer" subsidizing but "Archer-Daniels-Midland (ADM)" subsidizing, you meant, I assume. :wink:

Yes, them too...
