as the title says i just swapped an obd0 b16 into my 91 crx.....ran great till alternator went out, changed the alternator now after 3000k rpm it boggs out and misfires....waht is the problem

 

ttt i need help all!

 

ttt

 

its in limp home mode thats my guess... check the ecu for any trouble codes that are showing up

 

where do iget the codes? how do i read the ecu? would help thanks...im a noob to hondas thanks all

 

stop going to 30000000 rpm's its bad for your motor!!!

if you mean 3k then it could be limp mode, check the LED on the ecu with the car on but not running.
Count the flashes, long = tens place, short = ones place.

 

can we go into deeper detail on how to read the ecu? still not under standing...thanks

 

i get a pause then 4 flashes...what does this mean?

 

i bet it's a distributor problem

 

i need to know for sure!

wow, what kinda stroke kit did you use to get to 3,000,000 RPMs? Must be crazy horsepower

Seriously though, what model Rex is it? Did you have MPFI stock, if not was installed properly? More info please.

 

Get urself some new spark plug wires and while ur at it some new spark plugs

 

code 4 = crank angle sensor.

Turn the ignition off and remove the fuse for the ecu. Wait 10 sec and see if you get code 4. If not problem solved. You may want to check for a poor or loose wire at the distributor. If you still get code 4, you have a bad distributor.

 

thanks everyone im workin on it
