So I cleaned the MAF sensor. Still no improvement I can notice. So... after we cleaned the valve of carbon, engine light went away, then came back same day, stated it was O2 sensors, then went away a couple days later... another couple days later it came back... o2 sensors again... now its gone away... =S no engine light now but still feels like its not giving as much power as the VX use to provide.
However, the hose that goes into the FPR (Fuel pump regulator) came off easy. I can see there are cracks at the end where the hose goes onto the pipe of the regulator. Could that be the cause of all this? That hose being a little cracked allowing air from outside come in? I didn't have the chance to take the FPR completely off cause we haven't been able to have at least a day off for more than enough time to check the part.
Just and update/FYI, while stopped at a restaurant my sister kinda pushed the gas a tiny bit while in park, engine revved and went back down to normal, then about a second later it revved back to 2000rpm by itself.
Additionally, when the doing a cold start, it starts fine, but sometimes I can hear an 'errrrrrrrrrr' while engine is running. Its intermittent too, it does it for a split second or a couple, maybe a few more. While the engine is still cold and you start driving, the engine sounds louder than normal and seems like its not switching gears smoothly. This only happens when its still cold. After warming up it performs and sounds fine but the errrrr noise still present when going slow speeds or stopping at a light. I'll try and take a video to post here so ya'll can understand what i'm talkin' about
Where is the fuel filter? I should probably change that as-well anyway?
Should I just go ahead and replace the FPR? Never been changed since we had it and its now at 140k+ miles.Got it since 85k+ miles.
If all that still doesn't help -.- i'll just replace O2 sensors.
After that next project is the ABS... Then the steering play.
Thanks guys!
Randy.
