until 2 days ago. This time there was no limp mode but the engine was lacking power and didnt want to rev higher than 3k (i bring her to 4k alot, hence frequent ATF fluid changes). Oo late to go to autozone so I went home disconnected the battery, checked the fuel car (random but I read it somewhere online) waited 30 minutes and the light is gone. I drove her hard yesterday and can say she improved as the day went on but am waiting for it and have no explanation for it.
Somehow I think this all goes back to the big recall for the vtec rocker springs. Possible reasons for a "cylinder 1 lean"
-maf sensor or ignition issue
-fuel system issue
P0171- fuel system too lean bank 1 (cylinder number 1 denotes bank 1)
1) Large vacuum leak
2)Fuel system concern
3)Ignition system concern
4) MAF sensor faulty
5) HO2/AF ratio sensor fault
Things I have done so far.
removed all parts leading to the engine to get a better look at hoses for any punctures or tears and to see if any buckle under acceleration. Nothing but I did notice of the two large hoses leading to the passenger compartment, one was showing wear (I assume that's to the heating core but am not sure). I might replace that going forward.
Still cant get to the bottom of that sound, any advice would be greatly appreciated!
have the same problem?
