I got this weird miss-fire... HELP!
Im going to my mech this week, but
I was just curious of what you guys think.

When driving Im getting this spitting and
jolts in the seat, Im positive its engine related and probably on my mech can find it, but its around 2000rpm now, and when I stop "sometimes" like at a stop sign, but not using the brake or any accesories it bump bump bump, and then dies. It starts right back up and does it again after driving. I checked for the miss-fire in my parking lot, I slowly REV'ed from 750-7500 and only got a little one around 7000 but thats all good.. ANYONE KNOW WHATS UP WITH MY BABY?

how in the heck did you get a 97 fd? in anycase, you might wanna check if your gaskets for the intake system are all good, any leak will make you idel too high. also, you might wanna check if you tightened throttle cable a little to much, a friend of mines did this and ended up with 1600rpm idle. its kinda odd that your injectors are at 100%, perhaps one of them burnt out and is stuck at 100% dutycycle. also what do you mean by normal injectors? if you mean stock injectors on a T04R and all those other mods, im suprised you have not had more problems.

Do you have any pics of your car?

I had a similar problem, it turned out to be the water temp thermosensor. When this sensor goes bad the Power FC overcompensates fuel mixture and goes really rich, and floods. Then it has problems hot starting. I don't know if this is your problem, check your sensor menu on your power FC and check the voltage on your h2o temp thermosensor. I don't know the specs for the '97 FD's so you'll have to get that from Mazda.

With that single turbo setup, it is tough to believe he is on stock injectors. Aren't they usually 100% at like 330rwhp? He has to be pushin a hell of a lot more than that! and what the hell is a wastegate exhaust and Cricular Dark Gold Wheels? Also, Trust Big *** new type intercooler? huh?

Well ya I have a 97' cuz im here in Japan. Im shootin 425rwhp on my stock injectors. HAHAHA see you guys dont have **** like a wastegate exhaust! Im sorry.. Not to sound like a dick. Also the Trust intercooler was put in by me mech, I dont know the exact model but it's big as ballz front mount. ALSO Circular is a company just here in japan, the wheels are light as hell, I cant remember how light, but easy to change when I use to drift

ALSO a pic of my car is coming soon, if it ever stops raining here, its the rainy season. I hope I can get one this weekend...... ALSO my problem was fixed, I had to wait for this driftin bi*ch to get out my way, with her dumb as ****.... ALL IS well... I went rich around 2000 for some reason, maybe weather change, or comp problem.... I went rich at 2000 so we just tuned it out a little and all good now. It was hard to see because I dont have a rich/lean meter just exhaust temp...
Thanks for the words of wisdom though
