WTH happened to my rig ?
I need some help with this one as I have no idea where to start troubleshooting. here's the story.
Thursday morning. its about 5 degrees outside and I am on my way to work. after about 5 minutes my idle starts to get really rough and starts surging between about 400 rpms and 1000 rpms, I have to keep my foot on the gas to keep it going at stoplights. I turn around and head home and I get a couple of really hard shifts and my check engine light comes on. I get it home and check the codes and I get these.
116 -engine coolant higher or lower than expected
636 - tranny oil temp higher or lower than expected
126 - manifold absolute pressure (MAP) or barometric (baro)above or below normal
114 - air charge temp sensor higher or lower than expected voltage
128 - MAP sensor failure / vacuum hose damaged or disconnected
334 - EGR closed valve voltage high
it has been parked outside since, I have been a little under the weather but today I went out to look over the vacuum lines and make sure they are good and they are.
I started it up and and it idled for about a minute then all of a sudden just died - NOW it wont restart at all, just cranks.
so I unhooked the battery to hopefully reset everything and it still will not start, just cranks. The tach does bounce
I checked the codes after that and I am getting all of the temp codes again.
116, 636, 126, 114.
It is about 10 degrees outside now.
Does anyone have any ideas on what the hell could be going on ? she has ran great until thursday and I have not had any of these codes before, then all of a sudden I get hit with this shitstorm of codes. I did not overheat the engine or tranny in anyway.
Thanks in advance for any help.
