Didnt really notice it before or had any idea...does the ecu really blink constantly? I had my check engine light go off this morning but when I checked for codes a few minutes later...turned the ignition on then the ECU light just blinked every 3 or 4 seconds...I stopped counting after 45, haha..I hope my ecu didnt make a fool out of me for actually counting that high.

 

It usually only will blink a couple of times during startup while the cel is on if there are no codes. Sounds like it might be a code 1. Does it blink once and then pause and then blink again?

 

it shouldn't constantly blink no. like the person above me said it blinks a couple times when you first turn the car on but won't keep blinking

 

Its like a constant intermitent blink...looks like an alarm led light of some sort that just blinks constantly on your dash every couple of seconds...

 

Sounds like code #1 to me. It is the oxygen sensor. If it is the stock one that has tons of miles on it it probably needs to be replaced.

 

and if it needs to be replaced just go to a junkyard and pull one off.

 

I drove down to LA and back last Sunday (800 miles) used a chipped ECU...Anyway, i posted a thread about the motor hesitating under 4000 rpm after flooring it a few times...probably ran too rich and covered the O2 with shiit. I only used the chipped ECU because I'm getting a VSS code on the stock one...I'm fixing that tonight but thats another story...Thanks folks
