another CAT issue and questions
why not go with cat deletes. Unless you have local emissions testing that doesn't allow it. I cant do it here in CA and parts here are about 3k. I believe you can get away with taking out the rear 02 sensors with no codes... There are others here that have done it and hopefully they will...- buildingdoc

03 expedition a/c compressor ?
You can replace the clutch, but you have to remove the compressor to do it. . The guy at the shop is doin you a favor by doing the whole compressor... if your clutch is going out the compressor is right behind it. If you only do the clutch you will be doing a compressor later- buildingdoc

air conditioner warm at idle
I would never ever put sealant into a closed system. This is just a restriction waiting to happen. If you put sealant in, it will react with any moisture in the system and harden inside. That cheap fix may result in a full system replacement. Compressor, condenser, evap , and lines can be...- buildingdoc

AC Compressor puked
if you discharged all your refrigerant, you don't have to disconnect the compressor. The system has a low pressure cut out switch that prevents the system from operating without refrigerant.- buildingdoc

Weird Idle issue...
Pcm reset via battery disconnect. No change and added 1500 miles with no change. Guess I will take it in to get scanned and maybe something can be seen on the monitors. Did the gotts mod and saw a pretty good increase in milage on my trip. Over 400 miles a tank and one of them was 85 octane...- buildingdoc

Screeching noise when engaging starter
Could be the starter solenoid not engaging the teeth on the gears. may turn into hitting it with a hammer trick. You could pull the starter and have a buddy ( a strong buddy) manually turn the engine while you inspect the flywheel teeth. Just a place to start.- buildingdoc

AC quit blowing cold
Find the large of the two lines to the compressor. See if it is cold. Should be. Also check and see if your heater valve is open by finding the 2 heater/coolant lines to the firewall and see if they are hot. If so and your heater is not on, then that may be the culprit. also +1 on the blend...- buildingdoc

Weird Idle issue...
Thanks for all the info. That's pretty much what I was looking for. I was thinking there were just a couple contributing sensors (MAF, IAT, and O2 sensors) and then the IAC was adjusted to satisfy those sensors. I did semi clean the TB right about when it started by spraying the TB cleaner...- buildingdoc

Weird Idle issue...
Ac on or off. Only condition this happens in is when the engine is warm. Cleaned the maf with the spray designed for it and followed instructions as I understand it can be a $100+ mistake. Just trying to figure out which sensor is screwing with idle control so I can replace it without...- buildingdoc

Weird Idle issue...
Okay... here is the patient 04 expy 4.6L NO Codes. when engine is warm the idle surges. Jumps from 700-900 and also makes a humming/fog horn noise between the MAF and the TB... seems like the IAC is constantly opening and closing raising and dropping the idle rapidly. I had changed the IAC...- buildingdoc

A/C valves
Check the larger of the two lines and and follow it from the compressor back to the firewall. It should be on that line. Also be careful to keep the can upright and understand that you are going to lose the refrigerant again eventually. I would check the heater valve first to make sure you...- buildingdoc

A/C condenser
I would change a drier on an ac system any time the system has a leak or opened for any time the system is opened. Replacing every year is a little over kill. I would go every 3-4 years maybe. Not a bad idea to add dye to identify future leaks and doesn't hurt the system. Flushing the evap...- buildingdoc
