Well today I had had with my goddamn car pulsing. I have been trying to figure out what it was for about 2 hours now. I checked all my grounds, and i also ran a code tester and i pulled 5 codes. Both O2 sensors, Knock sensor, TPS sensor, and speed sensor. I replaced my speed sensor a while back cause my speedometer wasn't working and i was wondering why it was reading a bad code. Then I unplugged my o2 sensor and my speedo started to work, WTF. So im guessing I just have a bad wiring harness. Im also guessing thats why my car pulses too, so what Im asking is where could I find a wiring harness(other then the dealer) and what kind of price im looking at spending.

thanks

It would help if you tell us what kind of car are we talking about.....

To be honest, it seems to be that you have a bad ground or a "shorted out circuit" somewhere. Have you checked for any blown fuses? Is it judt the neddle pulsing or is the motor itself pulsing?

Anyway, go to a junkyard. I just saw 2 96-98 civics at Pick-N-Pull 3 days ago. The motor harness was still there. Price, it cant be more than $50.
