annoying stutter....
I'm stumped on this one...
I've got a b18b in my 95 si hatch.
It will stutter when I floor it through the gears. It will stutter off the line in 1st (not going anywhere) and then BAM it'll pull like a mofo. If I'm cruising at about 40-45 in 5th and floor it, it just stutters til I let part way off the gas.
I've tried 2 differnt throttle position sensors. I've replace the cap, rotor, wires. The mechanical timing (cam gears and crank) are perfectly aligned. The ignition timing is perfect, and I've tried it advanced and retarded. No codes are being thrown.
If I let it idle, it will stutter ever minute or two. If I hold the throttle with the car sitting still, and keep a constant rpm, it will fluctuate about 25 rpms up and down. That doesn't seem unresonable, but still might be a sign of what's going on.
I'm just stumped on this. It will stutter to the point of not wanting to move at times, and this is my daily driver. The motor has been in the car about a month, and ran great for about 2 weeks... Now I'm just frustrated...

I haven't touched the fuel pressue. The motor is completely stock other than an intake for now... I wanted to get it stable before messing with anything...

spood: the dizzy was replaced with one from another teg because the intake got pushed into the cap and broke it.
jeterkm02: I'll replace that this weekend. I have one sitting on a manifold at my buddy's house an hour north of here!
Any other ideas on what it could be?
