Thread: Bogging roblem please HELP

no i have not been able to fix this problem

engine was a jdm swap and no actual CEL was lit

check for leaks in the intake before and after the maf sensor. i have a feeling you are losing meterd air.

so i had chris check out my car again but this time i was lucky enough to have him plug up his lap top and work his magic,his computer came up showing Bad knock sensor and bad cooalnt temp sensor. if i understood him correctly he basically said since the sensor might be bad the ecu thinks the car is over heating which keeps the fan on constant and puts the car onto ""Limp mode""

one problem though.we went to switch out the knock sensor and it seemed to not fix the problem (the computer kept showing bad knock sensor)

i got a hold of a new harness which i plan on putting on sunday and getting a new sensor hopefully this clears up the problem

hope everything works out

changed the coolant temp sensor and still no luck i ran out of ideas....lets say the tps is set at .56(which it is) i know it should be at like .44ish ...would this have anything to do with the hesitation?

have you tried a different MAF?

TPS setting should be between .45 and .55 volts. If yours is at .56v, then its too high. I try to set mine around 47-48v.

Also do the same test with the throttle plate all the way open (WOT). It should be 4.0v
If its not close, you may have a bad TPS.

Forget about the tps for now Martin. You're car isn't going to run properly until the coolant and knock sensor codes are cleared, and since we swapped both of them out at my house and they're still failing, my advice remains.... swap out the harness and take it from there.

listen to this man ^.

stratton.

yes i know i' have been slacking haha i just haven't had time to stay late at the shop for my own car...its always been for my dads friends cars and stuff....now his new car is whats been holding me from being able to get my car running good ...but tomorrow (tuesday is the day i shall do one side job and stay a bit later to finish up mine (put new harness in/on) im praying to god this is the problem ...which kinda makes sense according to chris' laptop .

so tomorrow one axle side job and then my car shall enter the shop hopefully one last time before it goes in again to put the snail on lol ...ill keep you guys posted
