Need Help diagnosing a miss.
Hello all, I have lurked on here for years... hate to join with a problem but it is what it is...I am having an ongoing problem for the last few weeks of a random miss on my car. i have changed the following parts and done the following tests.
new...Fuel filter, pv valve, plugs, wires, cap, rotor, maf, coil, IAC, and TPS.
I have done a key on engine running test and KOEO test and only gotten an EGR code. EGR is deleted but haven't had the car tuned yet. Car has is idling around 26 on the vacuum gauge. also have replaced most all the vacuum lines and cannot find a leak anywhere.
Only things im down to now would be TFI and Hall effect sensor but my work schedule this week is gonna limit my time for a few days and i'll just have to drive it and deal with it.
It will randomly miss/cut out feels like it is dropping a cylinder. Started doing this not too long ago after doing perfect for 2 of the 3 months i have owned it. I bought it stone stock figuring it would be good for a daily as it has been averaging around 22-23 mpg. I am still happy with the car but want to figure this out...
another odd thing i have noticed since this problem arose is that when starting the car the tach jumps up and down a lot... almost to 1k and i know that starter isn't turning the motor over that fast...lol.
open to suggestions on other stuff to check for so i have a list to go down on my next off day. Thanks for any help in advance.
