1995 E420 Stalls runs rough

[lebstyle]

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.

[lebstyle]

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.

[lebstyle]

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

[lebstyle]

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.

[lebstyle]

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.
