Power lost need helps.
 

ok so ive recently my 1988 rx7 fc has been at a lost for power and for some reason it happened when i stripped my interior. but anyways -.- im not sure if its my injectors or a vacuum leak or spark plugs miss firing or anything else -.-. how can i check if its any of these things?

What kind of battery voltage are you seeing at idle and what voltage while driving? This could possibly be an alternator problem.

im at about 10-12

Voltage should be running. 13 to 14 v

and how old is your fuel filter?

don't tell me "i don't know" either or i will smack you.

fuel filter is brand new. i change it every 8-10k miles. so maybe i need a new alternator

From Vegas to San Jose!? You must have long arms... lawl

Don't go out and buy one just yet. If you don't have a way of testing it, you can get it tested for free at most auto parts stores.




P.S. - If you need a new alternator... Look into the 130A Ford Taurus alternator swap in the FAQ sticky. ;-)

i'll be going back through SJ in like 2 weeks or so. :p

does the car have cats on it still?

NOT the FAQ sticky. I meant the "2nd Gen Archive" sub-forum. blah

my car has a bonez super flow cat on it with stock down pipe and y-pipe and mufflers.
my alt ranges from 10-13. engine off but power on it sits at 10. car on at idle 11-13 verys on if the head lights are on

Doesn't sound too bad. According to the FSM, alternator output test (at hot) should show 13.5V. This is factory, though... Your car is 23 years old.

Just for shits, get it tested at an auto parts store... Most stores do this for free.

Before you replace your alternator (IF you have to) consider the 130A Ford Taurus alternator. I run this alternator with absolute perfect voltage, and no issues whatsoever.
Only problem is... This superior alternator will not fit under the stock top mount intercooler.
