FIXED FINALLY!!!:
Trying to fix my low idle since last spring cleaning,checking,replacing!!To find out (not visible)there was a fine tear from the rubber coupler on the intake!!! I checked and checked,felt nothing at the time but,decided to disassemble everything and saw a fine tear underneath the lining of the coupler.Fixed my low idle,quiet blow off valve sound,smoother ride down hill on the hwy(less sensitive to throttle)......finally!!
I thought I had fixed this low idle in warm weather thing by replacing the coolant temp sensor but,it is starting up again.Low idle (200 rpm)to almost stalling only happens when the weather gets warm/hot and it has been sitting outside.I have weeded out and fixed a lot of things last year including
-Cleaning IACV
-Adjusting and set TPS with/multimeter & feeler gauge.
-Checked hoses
-Replaced cap/rotor/plugs/wires
-Replaced 02 sensors./coolant temp sensor
-Cleaned build up from elbow hose on EGR.
-Replaced bad capacitor in ECU awhile back
I really thought coolant temp sensor would fix it since that's what it reads off of first before the car gets to operating temperature then reads from MAF.Any ideas?What is getting warm/hot that it tells the ecu to idle so low on start up?
Thanks for any input
