Ok, my fellow stykers owners, am reaching out here for some help. I have noticed that my engine kinda stutters or cuts in and out in the lower gears... like 1st and 2nd. If I am putin along (steady thottle) around 30-35 in 2nd the engine sounds like it cuts off and back on. The engine rpm's don't seem high enough for the rev limiter ( if it even has one) to kick in.

I have no problems in higher gears, so I am thinking maybe the tuner is having a problem tuning in bottom end. ( just a hunch )

I have talked with Phil from Cobra, and we talked a little about this and he gave some advice on what to check.. ( the connection with the o2 sensor). I told him that I would ask around and check the connections before I call him back.

I would like to see if anyone else having the same problems... modded or stock.. If you could please post your results as soon as possible it would be greatly appricated. I would like to try and get this solved.

Thanks everyone!!

Hey Urban is this a new problem or has it been going on for a while? Reason I ask is if it is brand new it could be a gas problem. Bad gas or dirt in the gas. I had this problem at low speed after one of my fill ups. I put in the highest octain 93 and it cleared up, then went back to 87 the next fill up and everything was fine. Just a guess, couldn't hurt for one fill up.

Hi Urban,

I noticed the same thing in 1st and 2ng gear. I usually fix this by accelerating a little. It is not really a problem, but a little bit annoying. My first service is next week, I will talk to my dealer about it and keep you guys informed.

Thats what mine did after I put 20w-50 oil in it so I blamed the oil and went back to 10w-40 and it hasn't done it yet. I really doubt it was the oil and can't see how that would of caused it but so far thats the only thing I could figure out that was causing it. I don't know what oil your running but if you have 20w-50 in it I would try a lighter oil. If that does fix your problem then I can sleep better knowing that was the problem 8)

I am runnning Chevron, 89 . I will try another fuel as far as the oil I running this in it http://www.amsoil.com/storefront/mcf.aspx

I am kinda glad to hear others are having the same issue, but also bummed out, because I know how annoying it is.

Thanks for the replys!

Sounds like surging from the overly lean closed loop system the ECU runs at low throttle/RPM.

I posted a link to a fix here.

not sure if it would work with the Cobra Auto Tuner??? Anyone know??

I'm pretty sure the auto tuner is already doing this if not something very similar.

Mine did same thing until I put Autotuner on. This also fixed shift points dramatically.
