Would someone please tell our less experienced 'savers to use the pdf helm manual! Okay I guess I will. The manual shows everything and is pretty good at instructing how to check codes with the service port off the ECU. SVOboy has a amateur mechanic's wisdom well beyond his chronological age.
All you need to do is google "honda civic helm pdf" and go down the list to the General Tech Help hit. Download and you've hit pay dirt. It works today so don't delay and download it!
Anyone who tries to repair a Honda without the helm manual deserves the trouble he got himself into. Hell, it's hard enough even when you've got one!
Dude: You are being belligerent, stupid and ignorant. You want to pay your mechanic to fix the car, but want to beef, go beef at him. As far as experience, education or anything else goes, I believe I am as good as any mechanic you can find, only with a whole lot more education. Before you go blasting the folks that were trying to help you, you ought to consider the possibility that they might know a whole lot more than you think. The guidance you were given was solid, sound and based upon your information. Garbage in, garbage out. You wanted help, you got help. That help was not based on wild armchair whoopela, it was based on some hard core, hard learned experience.
Your pissed cause your mechanic did exactly what you were told to do, tough go find some other place to...
The CEL being on is what is causing your non-hesitation issue (it's ignoring the O2 sensor now and running open loop all the time, decreasing your gas mileage)
You will go out and buy a metric socket and wrench set for cheap
You will be able to work on your own car through our help
You will be able to save a sh*t-ton of money doing it all yourself
The high idle is either a messed with idle screw or vacuum leak, trust me!
Once you get the CEL taken care of (either get your mechanic to re-install the old one once he SOLDERS the old wires back on the old sensor or buy you a new one from Honda), turn the idle screw clockwise until it is snug (once the car is warmed up). Then turn it counterclockwise until your tach is reading about 600RPM without the climate control fan, A/C, radio, lights or anything else on in the car.
I did buy a socket set. It's a bunch of metric sockets with an extender. I'm ready to work! heh. I want to uninstall my ECU and install the new one. I can use my socket set for that?
