I just put in my 94 Ex intake manifold on my 90 Civic Dx and my ecu reads code 4 for the crank angle sensor and code 16 for the injectors.
Any assistance out there. My car starts up but it runs real sluggish because the idle is really low.
Desperate for some answers because it is driving me nuts!!!! Help!!!

 

Are you still using your dx dizzy and ecu? If so there's one of your problems. Im currently trying to get my car started and I know how much of a bit#h this is

 

adjust the idle nut on the throttle? (quick fix for now?)

I'm running a Si dizzy but had to use the dx plug because I didn't have the Si plug in. So, I spliced the 5 wires to the dx plug in and left the 2 blue ones out for a straight splice to the ecu. Still, getting problems. Don't know what to do.

 

Have you checked to see if you PGM-FI main relay is going out? I got that code for the fuel injectors month's ago and that what was wrong with mine.

 

I got that changed maybe 2 months ago. Let me go try one more time to start my car.

 

Wait a minute, the the two wires, (blue/yellow and blue /green), aren't hooked up? Dude, that's your problem. Get those wired up.

 

b/y and b/g are not hooked up! well thats it man! they go to cps sensor.

C1: IS BLUE/GREEN
C2: IS BLUE/YELLOW

ON THE ECU

 

they are hooked. they are running straight to the ecu. I just tried my car again and still the same. code 4 and code 16. I wonder if my dizzy's bad?

 

sure you have them wired right,not switched?

 

I just got my car started, and that was my prob. Good luck with yours.

 

i had the same exact problem when i used my dx dizzy connector there are two white wires try switching them!

 

try switching the b/g and b/y wires chance that the got switced around ......Injectors that could be from bad injector resistor box....bad ground wires on injectors.....lots of things......

low idle check your timing......ajust the t/p screw ......I did this whole shin-dig about 2 weeks ago...I still have lots of problems......mine with the vss, and somtims an electrical overload......
