I did but I will check again. I will also check the ect as well. Thank you

I have check for vacuum leaks before, couldn't find one. Did the MAF test. Still got the o2 code. However, after reconnecting the MAF I have not had the code come back on. Still getting bad mileage though. Check for leaks again?

So I have now replaced the correct o2 sensor. Still no change. If I reset the codes after I start my car the code will stay away. But after I turn it off and turn it back on I have about 3 min before it comes back on. Maybe MAF sensor?

I have had poor mpg, slightly diminished performance. I have had the car for 50000 and almost nothing but the basic oil changes and tires and such has had to be done. Originally bought a sensor, brought it to a shop and since the plug was wrong instead of not doing it they put it on the other front ...

I have an ongoing battle to figure out whats wrong with my 98 c70. Codes p0131 and p0172. what tests should i run or have ran for me to find out the real issue as to not replace and unnessecary part. I bought a sensor brought to a shop to have them install. told them the code and which sensor it was...

I currently have a 1998 c70 with a sch-900 for a head unit. I bought a wiring harness before I actually looked behind it. Went to switch and noticed all the extras in which i had no where to plug them into. What else would i need to buy?

Is there one rear cam seal or two

Would a rear cam seal leak so that it would wrap behind the motor and get on the catalytic convertor?

yes that is definitely my next task, don't want anymore misfires

Does anyone know of a good reasonable priced junk yard or something in which you can find less popular parts? like the plastic lens that slips into the rubber boot for license plate light on a 98 C70 coupe?
