1995 E420 Stalls runs rough
 

hi All,
I have a 1995 E420, wierd things have been hapenning.
Even since I changed the fan clutch and Radiator ( got Shredded) the car has been acting wierd.
It starts normally, roars like any v8, runs for about 10 mins, feels like it is suffocating ( not enough gas) then turns off. Then if you try to start it, it wont start, it will start backfiring ( Loudly).
If you leave it alone for about an hour and come to start it , it will start right away.
No Engine Light.

One thing i did notice when it was on in idle, and I felt it started to stumble, I thought I would give it some gas to see if it would correct it, but it just turned off, and wouldnt start for another hour.
Even if I am driving, it will stall on me.

Any Ideas, Thanks in advance

One thing to Mention, I just Read the codes off the reader ( the main One)
I got code 6 and Code 13.
Which are idle speed control fault and Camshaft position sensor Defective.
One other thing, Even if it starts running rough and I turn it off myself, It still wont turn on unless I wait 45 min-1 hour.
Hope than helps
thanks

The codes are telling you to check pins 4 and 7.

so if i use the code reader and read them off pin 4 and 7 and it should clarify the problem?
I am thinking the camshaft sensor code is just from me trying to crank it and keeps backfiring, I dont think it is causing the car to choke and turn off.
i will Read the codes and re-post
thanks

I looked at the code reader, there is only 8 pins and 4 and 7 are empty, is there somewhere else i should be checking?
thanks

You're on the 8 pin auxillary connector. You need to be on the 38 pin diagnostic connector which is in the black box next to it.

I am going to scan that soon, but one thing i noticed, once it starts and I keep my foot on the accelerator, the car will stay on forever, but once it warms upand I take my foot off the gas it will stall and wont start for another hour.

I just scanned pins 4 and 7, no codes on them at all.
any ideas?
thanks

One more point to meniotn, The ASR Light does come on sometimes, but goes away when i turn the car off then on, it comes on randomly, not everytime, and It did used to come on before I had this stalling problem.

Just a chance you have a blown fuse #4 at the base module N16/1 located in the module box at right cowl panel under the hood pull the cover and check those fuses you will see them on top of the module.Fuse #4 feeds power to fuel pump relay,camshaft adjuster,air injection relay. good luck

I forgot to ask have you checked the wire harnesses for insultation falling apart and shorting wires out at camshaft sensor and other connections

is it the main fuse box or the one that houses the 38 pin connecter?
but wouldnt that cause the car to never start?
its wierd b/c only when the engine warms up at idle it will stop, but when u have ur foot on the gas it doesnt.

where is the camshaft sensor>?
thanks

I checked the 4 ( 10amp) fuses on the passenger side, they all seem fine.

its mounted on top of the left cylinder head by the fuel rail at intake manifold area it should have a resistance of 900 to 1600 ohms.
