I installed the LT4 Hot Cam kit on my 95 and have been experiencing a low rpm hesitation whenever the car enters closed. It drives fine when its cold, but when it warms up the stuble occurs. I have done a search but haven't found an answer to my question. I am going to try replacing the IAT sensor today because I have read a few posts of this helping out some people, but does I am really at a loss. If it was my cam timing I would think it would occur all the time same if it were misadjusted rockers. I didn't have any problem before the cam install. At least nothing of this magnitude that I could feel so strongly.

 

I replaced the IAT sensor and that didn't seem to do it. It was a shot in the dark, but I figured for a 15 dollar sensor it was worth a try.

Anyone experience something simlar?

 

I got a problem on a new engine of mine. When i launch the car rolls a few feet drops to idle (while still at wot) then it takes off 5secs later.

 

I ordered a cable tonight and am going to try scanning it. Figure I might as well not go aroud guessing and spending money on things that I don't need. Hopefully I will be able to tell what is going on once I start scanning. I also ordered up a coil and harness to run my 6AL MSD box. I figured I might as well use it since I have it. Maybe it can help out some what. I'll let you know what I find out.
