Have you inspected the main relay? Maybe a solder joint is going bad. As for where to put a Fuel Pressure gauge, You could put it on top of the fuel filter, drill and tap into the banjo bolt. I haven't looked at a stock fuel rail in a long time so I am not sure what options are available.

I jsut swapped out another ICM and same thing. Must be fuel. I am going to order and install a fuel pressure gauge.

gotcha, thanks for info to know that is possible. I didn't know we could transfer to better ignition systems. I am leaning towards icm now also as this happens only at low rpms it seems. I wish i had a fuel pressure gauge hooked up so i can eliminate some things. I think i am going ot order one now and install it soon. As that is a useful gauge. So lower rpms i mean like between 1k and 3k. Has never sputtered so far above 3k. Sounds like icm.

Not necessarily. COP is Coil on Plug, instead of having one coil for all 4 spark plugs and relying on the rotor wheel and ICM, each spark plug has its own coil. I am using d17 coil packs which came on the first gen j series engines.
You have to get a mini cop kit harness and motherboard. I got mine from here:

Simon is an awesome dude, install wasn’t hard at all, just required some cutting.
For the COP holders, I worked with simmonstuning https://m.facebook.com/SimmonsTuning.
im happy with the COP kit, it actually helped the car idle better.
However, I am chasing down why I am having blow out in high boost. I think it’s due to a week Coil, since I’m running junkyard coils and not brand new ones. Which new ones will be purchased in the future.

Anyone got an opinion or possiblity? Hard thing to test when it is intermittently happening.

am thinking fuel filter, bad tank of gas or fuel pump. It wont let me edit my op. The intervals between it acting up now are getting closer adn closer. So icm wouldn't do that. Must be fuel or some wierd electrical problem. Oil from cam seal was spilling all over those wires back there. I thought it might of been that at first as AC went out one night also. Oil leak is fixed now. Time will tell as a pattern shows itself. Any thoughts are appreciated.

Engine sputters sometimes when accelerating but acts normal when restart
My car will sometimes sputter when accelerating and do it continuously but if I restart car it will act normal and accelerate just fine. Sometimes i can just stop and idle and eventually drive again with no issues but restarting engine it always fixes it. Also if i just come to a stop and let it idle while this is going on it idles just fine also. I was thinking fuel filter at first but it doesn't continue after a restart and the intervals between these symptoms can be prolonged byt are getting closer together lately. Am really at a loss. This car is a manual with stock f22a in it. No mods anywhere as far as engine goes. BTW there are no cel light coming on and engine never actually dies. It will idle fine if u just don't accelerate. Am thinking fuel pump, bad tank of gas or fuel filter.Last edited by zedjr10; 07-11-2021, 01:03 AM.Tags: None
