ya plugs will do it big time. i had that happen to me a few times. what plugs u running? currntly im running an ngk bkr6e-11, which is 1 colder than stock which is a 5 heat range. ngk's are like he only ones to go up in number and go colder on plug.

Well to be honest i got so busy doing othing things i forgot to swap plugs i noticed last night when i looked over and in my passenger's door sat my box of brand new ngk bkr7e's. So i know that is some of the problem but i would of thought i could at least get to 0 vac before they would start causing an issue. But i will be putting them in tomorrow. The same time im am doing the boost leak test.

Alsoi found this and im going to get it asap! https://www.evolutionm.net/forums/ev...y-package.html IT looks awesome.

 

what does this do? does it delete the maf?

 

speaking of spark plugs... which wire set is better

magnacore or ngk -> the blue ones from speed corps?

 

IMO, because of how short our wires are, there really is no need for big wires. I think the magnacores are just overpriced wires. NGKs for the win.

 

good because I already got them. Is there a kit for cylinders 1 and 3? not sure which ones... I need to buy 2 more or am I good with the 2 I have?

I know its confusing sorry

 

No, our cars have two coil packs and two wires. And before you go looking to upgrade your coil packs, its unnecessary. Your stock packs will keep up with almost anything you do to your car.

 

well thats great I could have saved $30. Oh well the blue does look nice

 

Update found 3 boost leaks today. 1 was a hole in the weld on the intercooler piping near the bov. 2 was the throttle body were i did the 4g93 intake there is not that plate on the side of the intake so new gasket didnt seal there i rtved that area and put a new gasket. Lastly was the egr gasket was leaking. Those were leaks i found and i just finished replacing the gaskets. Also the plugs i receaved from the show never really looked at them were bpr7es number 5534 as soon as i looked at them i was like shoot. I should have my back up pair comming in the main soon i always like to keep a second set of plugs on hand so i hope the other place i ordered from doesnt send me the wrong ones. Im going to try the local auto stores and see if they stock any of the correct plugs today. Maybe then my stumble will be gone!

 

i didnt think that the bpr series wouldnt fit in our cars. the bpr is a 13/16 hex where our lancers run the bk series plugs at a 5/8 hex. try the bkr7e-11 at the number 5791.

yep you are correct and nobody in my town stocks the correct plug so i guess i have to wait till my second set comes in.

 

Err..... This is starting to really bother me. I am pretty sure all my boost leaks are fixed. Idle air fuel two days ago at operating temps was 17.7 to 18 now it’s 14.7 to 15. And with boost leak tester on that rubber hose coming off the j pipe there is no boost leaks. Replaced the plugs with autolite < junk I know didn’t have njk's in stock but I have a pair coming in the mail. They are gapped to .30 and I’m still getting that stuttering/sputtering/shaking/vibrating during acceleration. Does anyone else have any ideas on what could be causing this? I am going to buy some new plug wires but these have only have 21k on them they are from a Mitsubishi dealership.

 

is there too much fuel going in, that was my problem during my first drive. going into boost would cause the car to jerk and grind and bump and fart lol. i had to not boost all the way to ivey when i got it tuned. it sounds just like ur problem. car would go crazy and much slower when trying to boost.

 

Yah it's fixed!!!! dyno tomorrow! i got evo scan and it said i had a miss in 2 cylinder and i replacede the coil pack now its's running like a champ.

 

So im maxing out my injectors lol. I knew i would be. Im running 12's A/f and at the top end i would say 5500 to redline im at 13:1 to lean for me need 440 injectors. Im running 6psi and my numbers are 201 HP and 187 TQ. 4th gear pull Will post up the dyno run Monday when i pull it off the comp at school.
