check to make sure the intake air temp sensor is plugged in
where is that located
after reading all the codes and checking wiring diagrams, there is a connector on the drivers side of the car under the hood,next to the valve cover towards the front, you need to check all the pins and terminals in it.
also on the back side of the head on the drivers side of the car. there is a little black plastic piece with on green wire going to it, trace that wire and make sure it is not rubbing on anything metal and shorting out
ok can i check it right now?
There is also alot of flashes for the PCM for some of the things you mentioned
Yes, I need to switch to Q&A to post you a wire diagram, you are going to have to check each wire in the diagram for a short
I also know of one more quick check to do if it is acting up right now
do you mind if I switch to Q&A?
it rarely acts up idling unless i goose the gas and then rpms fall and sometimes stalls that way but always acts as though its going to die
just after pressing the gas pedal and letting off fast
ok, goose it get it to act up. shut off the car, unplug the A/C high pressure switch, start it back up and try to get itto mess up again
is that the switch right up front of motor on passenger side for the air conditioner?
yes, it is attached to the A/C line close to the radiator on the passenger side
ok..yeah i unplugged it and it after goosing it did the same thing but did not die
Did you check the first two things about the connector and the plastic thing with the green wire?
is the little black box with green wire about an inch long?
because we found something like that little connector that was very corroded or meltled or something like that
yes it is
that little thing looks damaged
If it is melted you have a short to ground on the main power feed to most of the circuits
you need to trace the wire that is attached to it and find where it is rubbing on something metal
yeah it it kinda crumbly
that is the problem
is there still a wire connected to it?
yes there is
is that a ground wire?
no that is a power wire
that is and ASD relay output wire
it powers all the injectors, coils,O2 sensors, andmost of the sensors
the one we found is connected to a connector on the manifold. is it still the same one you think?
yes, that wire splices offto all types of places
can you tell somewhere on that wire what color it is?
oh it does..so we need to follow the green wire and look for where the wire is touching metal? is it green all the way?
it should have a little orange tracer line on the green
But yes it stays green to everywhere it goes, there is a few splices in the wire, you will probably need to remove the plenium to trace the entire thing.
the most common place I have seen this wire short is at the front of the exhaust manifold by the big connector on the drivers side
my husband unhooked that connector and started to plug it back up and it sparked and now cant start the car back...did he mess something up
No he probably blew the fuse
Fuse S in the PDC
it is a dark green wire with a light green tracer on it
let me look at it again
that is the power wire for the injectors, coils, short runner valve, 20 amp fuse in the PDC and the ASD relay is where the power starts
oh..can he just replace that wire and connector?
or will it short again?
you will have to find where it shorted, the fix the short and replace any part of the wire that melted, the little plastic piece is the capasitor it will also need to be replaced
oh ok...yeah it just crumbled around the metal inside
I can post you pictures of the entire circuit when I switch to Q&A
so now the very small plastic part is gone
how do i see them...this is my first time
you will get an emial when I post to it, it is easy
ok..and then i just go look at it?
yes, you can also type and I can answer in there if needed
can i save this im?
I dont know, it will show this whole thing in the Q&A side so you can see it
do you want me to switch it and start posting the pictures now?
