been about a month now, when i went to turn on the car, i put the car in drive and i could automatically tell there was a small difference. popped the hood and could see the engine with a lot of movement in it, more than usual. as i started to drive, i could see alot of knock going on. im guessing its false knock since i saw how much the engine was moving, regardless, when i rev the engine it doesnt sound as smooth and my boost gauge is erratic. the needle goes up as boost goes up but its not a clear reading since it shakes between 5lbs as it goes up. same as my fuel pressure gauge, as i drive , i can't get a clear indication of what my fuel pressure is since the needle shakes alot as well.
i first thought it might be a boost leak, but i dont recall ever seeing the gauge needles reacting like that because of a vacuum leak.
ive checked maf, had it unplugged , ran worse, so i guess it wasnt that.
replaced fpr, ignition module, coil packs, spark plugs, and o2 sensor.
would a crank sensor, cam sensor, or bad fuel pump cause the erratic gauges? btw, i do have a double pump set up and unsure if there would be one in the gas tank as well.
im gettin low on cash and this is my daily driver, so im trying to pinpoint now, instead of replacing everything that i might have thought was wrong. ive read alot, but havent found much on the gauges reacting the way they do.
i can get the scanmaster readings later on today. but from what i remember, the only thing that changes alot is the IAC readings. i'll set it to what its suppose to be, but a couple of days later, its off again. then again, i just changed my 02 sensor which was also bad since my readings have been a bit different. so i will get new readings today.
appreciate the help , thanks.
