limp home mode
ok so bart (portabuddy) just called me (I'm at work and hes on the road) snd told mr that he just got a check engine light on and the car is chuging and sputering anywhere over 3000rpm and it will not build speed so it is in limp mode, wondering if it's a electrical thing or if he really sucked up some water as he dose have a CAI please adives, also I would love to run out and diagnose the car but I'm stuck at work till 12midnight
 any thoughts? (he has a 06 Si (haby)) Last edited by KMM; 07-08-2008 at 11:08 PM. |

i might add that the battery is good, there is a second deep cycle batery hoocked up. the car did this before when washed once it just didnt go into limp mode. then the last time was durring a MAJOR rain storm, the car felt like it was on two cylenders. then it evened out...
what i did was let it idal, then increase RPM slowly, so if there was any water in the cylender it would exit, then blip the trotle and once there was no sine of stalling shaking, surging, hesitation, i'd WOT it for a min to make sure its all cleaned out. well this time was differant. again in heavy rain. but this time the car forced slow acceleration and limmited RPM's to 3000 no more. kmm's goona unplug the battery, idle it for a bit then take it for a boot... then i'll probly get a compresson test done. just in case. its probly just a loose plug or a bit of water on the MAF but who knows...
