PI intake installed and I'm missing

bleau · May 24, 2008

Hey Guys,
I installed my pi intake ran normal for a while.
Now it seems to miss a little at around half throttle under load.
I've heard that this is the computer re learning the intake, but it did not happen right away.
Anyone else have this or do I have a problem somewhere
Thanks for the help

Check for a vacuum leak.

Could have gotten some coolant in the plug holes. Check those out and dry them real good. I did that and my missing went away.

+1 to that too. Last time I washed my engine bay, I got water down past the plug wire boot and I had a miss. Also check all the obvious stuff, like making sure the plug wires are seated properly. I just replaced my stock plug wires with some 9MM's and didn't have one of the wires seated all the way. At WOT, it felt almost like my car was being held back by something. I pushed it in all the way and it cured the problem.

Just checked the spark plug holes, had a little dirt in them.
My bad on that.
No coolant, I will let you know if that was it.
I wondering to if its a non related issue like bad plugs or something.
It didnt do this when I first got the swap done.
Would I not get a code if I was missing, I remember once I had a cracked intake by the water heater tube and got a code for cylinder missing?
Thanks for all your help.

Yes. There is a code for multiple mis-fires.

same thing happened to me on tuesday.. first time its happened.. except the miss was horrible. had to rev to like 2000rpm to take off or it would stall. pulled the plugs and had 3 that were pretty much pitch black and the rest seemed alright. it was brutal.

but back on topic, i'd check for coolant in the plug wells.. apparently its a normal thing right after the Intake swap.
