I was born and raised in saudi arabia, my dad tought everything there is to know about engines. I was replacing alternators and starters when i was in 4th GRADE!! Anyways over there the only place to get your car scanned was at the dealership and it was way overpriced! So i didn't know what the hell OBDII or DTC's were till I came to texas 3 years ago. (i knew what they were but never checked them) Basicly i was brought up the traditional way, diagnose by personal expierence and knowledge as well as elimination. I've noticed the people here think its "cool" or they know more about cars if they can say random numbers and letters put together and use all these acronyms! I'm sorry but for me getting under a car and all dirty and grimmy is manly, but when kids start saying all this random **** they've memorized off some forum or website they're not manly, they're the people that need to be walking around dressed in their fathers hand me down slacks and a tucked in shirt with a shinny stiff comb over! Oh yah, they should also have a protractor along with the pen case in the front pocket.
ANYWAY I've got a '99 cougar now and its giving me problem after problem (i'll post a new topic with all the issues cuz it'll be off this topic) but one of the problems i have is just like the one Fett has:

The IMRC was sending intermittent signals to the PCM and it was pulsing my injectors in an inconsistant manner. I replaced my IMRC and the problem never came back. Now typically someone would display those symptoms and everybody would tell them to replace their fuel pump and filter....which would have been a huge waste of money and would not have solved the problem.

I got my IMRC replaced almost a year ago, then about 4 months ago i noticed that the plastic grommit was missing so the rod from the IMRC wasn't doing anything! So i got that piece and replaced it but now, starting from maybe two weeks ago I have an ENORMOUS loss of power. My golf cart accelerates faster! I just retrieved the codes(here we go
) and i'm getting P9318. I looked that up and its: Battery voltage low (less than 10) I just replaced the alternator and battery almost a month ago. Also when i'm driving the battery light flickers on and off, sometimes stays on solid, and sometimes doesn't even come on. I'm about to go check all the wiring and do some voltage draw tests etc. anyone experienced this before and want to give me a heads up?
