Basically I am having issue with my idle hanging anywhere from 1500 to 1250 or so and it fluctuates sometimes in that range. This all started happening after I blew my FRPS. I've researched and tried most options just looking for anymore feedback.
Before the incident, my idle was find and sat around 850. Now it wont settle past 1200 most of the time. I know its not tune related because my car was running fine before the FRPS went up. This happened about a week ago and aside from the idle itself, I have no driveability issues.
Here's what I've already tried.
Replaced the FRPS twice.
Cleaned MAF sensor
Cleaned throttle body
Cleaned IAC sensor
Checked for vacuum leaks visually and w/ carb cleaner
Adjusted my Throttle position but no change at all.
Changed the plugs
Changed oil
Changed to new battery
Car still ran after unplugging the IAC valve, MAF, and TPS sensor independently.
I'm leaning towards a vacuum leak because on my boost gauge my vacuum is reading b/t 14-15 where I could of sworn it was closer to 18.
I tried the carb trick but still no luck. I pulled some datalog to see if some of my stuff compared to others is off.
Vpwr 13.5
ect 186
rpmsd 800.00
fpdc 0.17-0.18
iacdu 0.524
frp 40.000
iat 106
load 0.240
longft 0.810
longft 0.790
mafct210
rpm 1500
shrtft 1.000
spark 35.000
tp-v 170.00
This is all at idle and at this point my boost gauge was showing a vacuum just shy of 16 psi
Any ideas? This has me extremely frustrated at this point.
