Hello All,

Just completed an SR20det Redtop with an E5 ecu, stock AFM, fat o2 on an Datsun Roadster. Now of course I am having idling issues, misfire and running rich. So i tried to pull codes from the ECU and I get nothing. The LED does flash when i turn on the ignition, but that is all it does.

Procedure is:
Turn Screw counter clockwise and turn ignition to on?

Seeing if anyone has any in sight on this or come across this issue. and of course a resolution.

Any help would be appreciated. (with ECU issue and Rough idle)

BTW i've already tried the following for the misfire:

1. Adjusted TPS Back to .45 wasn't to off @.55
2. Cleaned IAC (new gasket)
3. Realigned CAS
3. Checked Coils. they are ok.
4. Changed Ignitor
5. Cleaned MAF
6. Checked for vac and boost leaks. none

:wtf2:

Thanks in advance.

Hmm, this one has slipped under the radar too long. What year engine and ECU are you using? I'd grab the FSM for that particular engine/ car and work with that a bit. It will have instruction on how to manually pull codes for a blinking light if it's an OBD-1 type of computer I think.

Here's a link to all the FSMs to look through and good luck.
