Today i was driving home and sometimes the car would stutter.. felt like it was missing.. It isnt load/gear/speed/rpm dependant, and will just do it sometimes for a sec. Oil pressure is good, it isnt going lean on the wideband.. and its still building boost normally. no cels. I feel its an ignition issue.. I washed under the hood today, maybe some water got where it shouldnt?

I did a 5th gear 'semi' pull on the way home.. just up to about 100-105mph, i was at only 60% throttle just cruising.. It was fine then too, ran normally.

Could water get into the spark plug boot/area and cause this? It was only a few hours after i washed it. I havent really done much looking around under the hood to see what could be the problem. Its a new cap/rotor from honda, as well as new plugs.. BRK7's, i have a spare set i may change if problem persists, as well as maybe pull the cap off and investigate under there.

Car has ran great all year. So could water be the culprit? I figured the heat from the engine would just dry it up shortly.. What should i look into first?

Setup is just a stock block B18C at 7psi, street tuned.

yes it happens.

 

I pulled the cap off the dizzy, pulled the wires, cleaned everything, and put it all back together and problem still persists..

I got almost all the way though 3rd at WOT around 7k it just backfired, and i let off. Sometimes it happens at 3k sometimes 6-7k etc.. Throttle position dosent matter as well as load.

I will swap ignition setups with my friend dizzy/wires and put in my spare set of plugs.. See if the problem persists.

Does anyone have any pointers on how to diagnois between fuel and ignition ? Im pretty sure its an ignition though. since it only seems to be happening after ive been driving for 15-20minutes and the cars been at temp for awhile.
TYIA!

 

Just went through the same thing last week. It turned out it was just my coil runs awesome now. Cheap and only took half hour

 

didnt do it yesterday at all... car didnt get a chance to get hot for along time only drove 15-20 min each way. Gonna swap dizzy's maybe today.
