In New york times, we are dealing with 90 degree weather. So on the way to work the car power shut down and on the screen it say (engine power reduce). So now when you start the car it shake like the car is miss firing. Is my car dead , or could this be a easy fix?
Got the car back yesterday, they say it need a Mass air flow sensor, throttle body kit and a map sensor. If I get the parts, can I do it myself?
Another thing do the 04 srx northstar v8 have a Idle Air Control Valve? and if it dose where it is located?
Automobile(s): 2007 SRX4 N*, 2004 Infinity G35 Coupe
Re: Bad Day
Caddy Dave..........can you add "V8" in your profile under "Automobiles?" It would have helped you initially get some help from others in this thread and in the others in which you have participated and asked questions about your SRX.
I just replyed to another post with this similar code.171 and 174. For me it was a leak on the PVC lines. It was the "dirty side" see the schematics on this forum. When i tried to take the pvc lines off the rubber fittings crumbled in my hands. Completely the source of the vacuum leak. I see this as a common issue with this era northstar. It drove me nuts and i spent a lot on mass air flow sensors etc. Please check out both your pvc hoses. It can be a cheaper fix than all those other diagnosis. (I like the comments to find a repair shop not a replace shop). Once i replaced these leaking hoses, and yes my engine ran rough, everything got better. No damn codes, smooth running engine. I hope this helps.
