    The True Cold Air Intake??????

    I'm suprised you don't suffer from loss of power sucking soo much hot air from the engine bay. Do you only drive yours in the winter? I know NM gets prety darn hot in the summer

    Low power Tranny/engine?

    Hello fellow Arizonan. Our 1st Gen's HATE the AZ summer temps! If you feel that you are loosing power, that could be a combination of a few things, your fan clutch ingaging and your Air Intake Temp being too high. When Air Intake Temps reach 140* F, the PCM retards the timing causing a lack of...

    What's the secret to removing the #4 coil?

    You also might have to remove the fuel rail on that side. If you are going to all that trouble, it's good practice to replace the spark plugs as well

    The True Cold Air Intake??????

    It says it right here " This may caused by the PCM calibration which retards the ignition timing to prevent detonation when the air inlet temp AIT reaches 140 deg F or above. " The AIT sensor is inside the Air Intake. You also have to take into account the a/c compressor running which adds a TON...

    The True Cold Air Intake??????

    I am getting my Air Intake Temp from a wifi obd adapter and I am using " Dash Command app " on my iphone. So far the hotest my " AIT " has gotten was 125* F. I will also note that the AIT does NOT raise as fast as it used to minus the header wrap, this helps when at a stoplight. AZ temps...

    The True Cold Air Intake??????

    Actually my main goal was to isolate heat soak from the hot engine bay getting to the Intake Air Temp sensor, another cause of retarded timing, please see: TSB 02-12-3: " Drivability, lack of power condition when operating in ambient temperatures above 100 deg F. This may caused by the PCM...

    The True Cold Air Intake??????

    And this is how it turned out. Bought this header wrap a while ago and finally got around to doing this. Been wanting to do this for a while because summers suck here in AZ. I had a previously started a thread that involved the whole " Air Intake Temp too high which retards the timing causing...

    Loss of power

    Was it a hot day? Sounds to me like the " air inlet temp too high and the computer retards the timing " issue. Did you hear a " jet engine " sound coming from the engine compartment? That's your thermal fan locking up. Both the Retarding of the timing and thermal fan locking up will steal a TON...

    Catalytic Converter replacement question

    Even for two that's outragous. Mine were aftermarket, but when looking at them they show no brand name, so I can't help you there. Heck I saw a complete header/cat coverter and y pipe on ebay for $500 shipped. Don't know if they are California approved though.

    Catalytic Converter replacement question

    4K is an absolutely rediculus price, that's what I paid for my Expy! Shame on you Ford for engineering that type of cost into your vehicles! I know that you need Cat's that are approved for use in California, I'm sure your local muffler shop will have the proper ones. Did you call around and...

    Catalytic Converter replacement question

    Update: Went on a long trip up to the mountains last weekend and the Expy did GREAT! You could really tell the power increase when going up long hills. The hills that would before cause the engine rev to 3500 to 4000 rpms now only has to rev to 2500rpm and I would actually increase speed going...

    Catalytic Converter replacement question

    Update: I bought a new Bosch 02 Sensor and installed this afternoon, what a pain in the ass that was! I do have a wi-fi obd2 reader and DashCommand app on my iphone-6. I reset the P1131 code and drove the Expy for a long time, no " Check Engine Soon " light and no pending codes after 35+...

    So does a clogged converter make a motor run too rich?

    Catalytic Converter replacement question

    Sorry for my last post, I must have been typing it up when you posted yours. Well at least the code is following the cat that had the blockage issue, which points to it failing because the cat went bad. I appreciate the help you have offered me 1955moose!

    Catalytic Converter replacement question

    After more research, it looks like it's the pre or first 02 sensor on the passenger side. Could it be that since the passenger side was the one that was 40% blocked, it got ruined because there was not enough flow and it overheated????

    Catalytic Converter replacement question

    Hi, So I spoke too soon. Started her up and before I pulled out of the driveway the Service Engine Soon light came on. After I got home from what I was doing, I put my code reader on and the code was P1131. This apparently indicates an 02 sensor somewhere on bank 1, just the thing I was worried...

    Hi. I'll look this afternoon and see if there's a manufacture/part number on them

    Catalytic Converter replacement question

    I asked the shop if they saw any other codes besides the " pending code " for the passenger side cat, he said there were none other than that one.
