My 91 240 would idle rough now and then, but now it idles rough all the time. Pulled a 34 code off the ECM which is the knock sensor, which made sense, because of the problem I'm having.

Most sensors were going for $80-$100 online and $100+ at the parts store. I found a MAE brand sensor for $25-$40 online from different retailers. So I bought one from US Auto Parts shipped for $40. Anyone have any history using a MAE brand KS ?

I know most all sensors are made by the same company,( kinda like how Frito Lay makes Publix chips ) but I was wondering if anyone has used a MAE KS.

BTW, my car is completely stock under the hood, (not even a CAI)
