Fuel or spark problems, or both?
ok, here goes.....Mods are in my signature.
I`ve been fighting this problem since 1st week of july. I`ll list what it is doing, then what i`ve checked and replaced.
Car has no power and turbo sounds funny when it tries to boost. At idle when i rev it up over 1500rpm i get what i think is a rich miss-fire....it gets really bad past 3600rpm when my secondaries kick on.
My afrs go to like 9 and stay there until i`m at 60mph when it goes to closed loop i`m guessing. i`ve test and replaced afm, boost pressure sensor, safc, ecu, cpu, fpr, fuel pump, air temp sensor in tb, plugs, wires, compression tested...that good too!!! its either not getting enough spark, or too much fuel. it pulled like a **** before all this happened.
when i barely step on the gas in all gear but first it goes super rich, and no power. My boost guage says 15 pounds, but its not putting that much through cuz it sound different. No oil seal leaking and coolant seals are good. no boost leak. exhaust has a burnt smell, i`m assuming its the pre-mix i`m using. I had a problem with my charging system, i fixed that, but i`m wondering when my fan, alt, and logicon went south all at once if this screwed something up?
Any help will be appreciated

maybe???? with only 40 looks? kinda funny, i shoulda put in my title.....mad jdm body kit pics!!! then i`d get a bunch of ricers to look huh?
what good would it do? I read alot of post and search alot instead of asking. I`ve found numerous problems and fixed them on my own.
Unlike others on here, searcing isn`t hard either, just time consuming. I have a fsm, $400 multimeter, and enough knowledge of rotaries to fix everything.
Hell, i`ve rebuilt my N/A to TII convertion from a gutless turd, to a very respectful rx7....jager can vouge for me too!!

oh, and by the way, i`m not a noob either....i just don`t have alot of time to sit and say a bunch of crap to try and get 10,000 post.....just cus a person has 10,000 mpost doesn`t mean they`ve encountered every problem an rx7 would have.

And maybe u shouldn t be so conceited glad u fixed the problem though maybe u should post what was wrong and help someone else e\istead of proclaiming u can fix everything and call people ricers So no one replied to ur thread maybe a better title would help (not saying u have a bad title) Most people here admit they don t know everything. Anyway I am just curious as to how u fixed it and what the problem really was (Not trying to sound like an *** or anything but u just seemed a bit condecending) anyway yea

How did i fix it? I`m currently parting it down and its gonna go to the bone yard!!! Thats how its gonna be fixed!
Trust me buddy, you don`t know me or anything about me. I spend 2 yrs in japan drifiting imports, and nothing has changed since 95 to now with a 87 tII.
But really, do a search on something really rice...like shooting flames, you`ll see y I don`t post or ask very many questions. Everytime someone does ask they get the check the fsm, which is fine, but when ur car is 7miles away from your online fsm and u have no printer, what do ya do???? Drive back and forth?
As far as me being concieded? Very unlikely. I help alot of fellow rx7 owner locally, and vs. versa......I just don`t have the time to well look at my posts, do you see 10,000??? obviously I have a job, a life and all that goes with it.
