Spark plug gap?

[Trigger]

ok the car is running like crap now. I regapped my plugs yesterday and the car seems to be worst. what gap is everyone running? my buddy with a 300z told me to gap them to .035 standard but I want to know what works for everyone here? at first i had them to 1 metric and i know that 1.1 is in the stats but i wasn't sure if making the gap smaller would run them better. let me know something if i dont hear anything then i am going to regap them to 1.1 and be done with it

Im using NGK BCPR6ES-11 and the car runs awsome. I left it at the gap they came with, which is the same 1.1

[USDM_OneVia]

Yup... same here. BCPR6ES-11 @ 1mm gap. Run's pretty good for me.

Did you check out your o2 sensor and my whole post on ignition timing?

Define "running like crap", might be a bit more help to ya if I knew what was going on. These motors are quirky.

running rich....when i hit the gas i get big puff of smoke...its spits and sputters...not excelerating like it should...I got to recheck timeing and going to gap the plugs tonight

uuuh, are your aacv, o2 sensor and pcv solenoid getting the right power? hehe, sounds like mine was..

you know there is a chance of that....my dash lights are kinda being weird and my clock resets whenever the door opens

LOL @ Trigger. I love electrical problems, don't you? I'm putting my new plugs in tommorrow night and recheck timing off of the #1 plug instead of the loop. My car seems to run well, but I thought I'd check to see if there is any differrence. I am getting real crappy gas mileage, but the power seems alright?

[slw240sx]

have your ALT checked out might just be bad and not puting out enough power for the coils

[r34 gtr]

whoa, float, thats me exactly!! power seems alright but i have spent $40 on gas in the last 8 days!! its really cutting into my bank account. my alternator is fine as i just got it rebuilt and the safc says im getting 14.4v. maybe my car just hates me, in which case im fine with it because at least there isnt a physical problem.

We'll see, but I think I'm going to be getting about 20m/g but I haven't been real easy on it either. Plus the first 20-30 miles were with the old O2 sensor (which, btw, helped my irratic idle, but it's still a cold blooded biatch) I'll prob do that stuff tonight and I'll let you know if my timing was off or not. Then either Joe can verbally abuse me, or I can verbally abuse him. The suspence is killing me! LOL.

well, im looking at about 6-8mpg currently. lemme know if you find out whats up. i used about 28 gallons of gas in a week and went less than 120 miles. no leaks in the fuel system or anything. its a pain on my bank account. it cost me more in gas to drive to work last week than i made after taxes. (only work four an hour or two after school).

oh, and i know its capable of good gas mileage because it used to get about 35mpg. id have to fill up once every 2 or 3 weeks. course this was probably largely in part becuase i was shifting at 2k rpm and driving like a little girl. but i only shift at 3..would habitually engine braking do ****e for my gas mileage?

[boost_boy]

I engine brake as well and yes, it will syphon extra fuel.

[slw240sx]

so im not the one who is constantly engine braking their CAs right?

[boost_boy]

I've always done it. I even brake from high-up in the rpm or in the high mph areas; it doesn't matter. I hear myths that it's unhealthy for the timing belt, but I always say "maybe for your timing belt".

[Trigger]

umm explain this engine breaking thing to me please

Downshifting to slow the engine down.

Downshifting so slow the CAR down (speeds up the engine)

oh ok i got ya
