#65 of 68 Can't find reader plug...:P

Anyone know where to find the plugin for the code reader on a 1991 MPV? I've looked both under the dash and all under the hood and can't seem to find it.
#66 of 68 mpv mini van what a joke 2001

i took the van in to the shop because bad performance when cold, after 10 miles it runs like a champ, if you stop and turn it off for 30min to an hour it runs like crap, then after app 10 miles runs like a champ, we have replaced the bad intake gaskets upper and lower, still no response, replaced coil, no response, took the intakes back off for soaking with chemical, then put it back together again, still no response, still missing, changed plugs, changed wires, still no response, now it shows low compression on #1 back next to fire wall, app 90 lbs, so i would assume we need to a 1000 dollar valve job, does anyone know what the hell ford/mazda has done to these engines, i know they say the intake gaskets were faulty from factory, but just issued new ones to replace them with it, seems a lot of people have the same problem, i would say to all people to have compression test done on the engine before you spend 2-3000 dollars on these vehicles. if anyone can tell me why this happened and how i would like to know. thanks

#68 of 68 Multipe Codes - Need Help
Dec 25, 2010 (8:12 pm)
I have the following codes showing:
P0300 - random multi misfire detected
P2404 - evaporative system leak detection
P0113 - intake air temp sensor 1/ circuit high
P0421 - warm up catalyst efficiency below threshold bank 1
This happens only when the weather is below freezing. Engine sluggish / hesitates.
This completely resolves itself when weather warms up.
What could be going wrong?
My theory is - the O2 sensors front (1) and back (4) are fouled up for some reason. But I could be wrong.
Anyone has clues about the root cause?
