It Idles ok and this problem only happens when the engine is at a normal operating temp.

I can gently pump the case and see the tach stutter and hear it in the exhaust. I can hear this when I drive. But If I floor it. It goes fine.

No CE light.
22.8 mpg average

tunes :

plugs, wires, cap, rotor

Old plugs were very clean and looked almost new. Burned even and no oil or gas on them. Never seen old plugs this clean. Clearly they had wear but they were fine otherwise.

The Pickup in the Dist went sometime ago. So We got a new coil first. Then A junk Dist.

About 5 months ago it started to stutter just a bit. Then got worse over time. Now its really bad and it miss's so bad You would swear its the exhaust. But the Car moves like a bat outta hell when you floor it.

To me this is rather like crossfire with bad wires or cracked plugs. So I tuned it and it diddnt help. Its not a gas issue near as I can tell. I tryed several brands or gas and grades and many cleaners and dry gas's over the last 5 months. Never even touched the problem. But im guessing I made the plugs pink for a while.

Looked for a vacuam Leak. No go. Looks tight.

I have been working on this for sometime and im getting agravated and close to inspection time. I hope you can help :)

Robert

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

Hi

I think its solved. For the time being anyway. I took into account all of your suggestions. Last week I added a can of gum out and a can aof drg gas to the take and drove it to about 1/8th of a tank and filled it with super. Oddly it got better slowly then ran almost perfect. But there was just a hint of a stutter that wouldnt go away. I googled spark plug gap for my car and found this:

Hold on here.
What motor are you talking about?

Because the GSR needs a minimum of.050" or else you'll get some serious stuttering, and the b16 is recommended to run an.044"

WTF motors are you guys running.028" on?

Pretty General but I tried it out and I also found out I have a lot of oil around the plugs. Need a new valve cover gasket.

Let ya know in a few days.
