(Real ? Pham) I need a diagnosis please
Now that the hot weather is back, somewhat, here in Atlanta, my car has started what I like to call "coughing". For some reason, whenever it is 70 degrees or above my car seems like it is running out of gas when I start it. I usually fix this my slowly reving until the car idles smoothly. At first I thought it was flooding, but I didn't smell gas anywhere in the engine when it was running. I am now at the conclusion that it has to be clogged fuel injectors. Is this a worthy diagnosis, or am I way off here?
thanks in advance for answers
(None of this really explains why it only happens in heat though

This is a common problem with K-jet systems. All of my K-jet cars have done it, always worse in warm weather, and I think it has to do with the pressure bleeding off in the fuel system and essentially causing vapor-lock at startup. Somewhere on this forum I read a detailed explanation about it. I'll post the link if I run across it.

suginami posted this in part in the following link:
"An HFM fuel injection system, as on 1993 and newer 300E / E320's, are fully electronic and a faulty OVP is usually the cause of poor warm start problems.
The early OVP's were bad and the failure rate is very high. The old part number is 201 540 38 45, made by Siemens, in Austria . It as replaced by part number new part # 000-540-67-45.
Now, regarding the recommendations on the fuel pump or fuel pump relay. This would be the diagnosis if you had a KE controlled 1992 and earlier 300E. The NUMBER ONE, all time answer, for hard hot starting on any K, K-Jet w/Lambda, or KE system is fuel pressure leak down caused vapor locking. This leakdown doesn't matter to cold starting as pressure builds almost instantly. On a hot motor if you release the pressure the fuel boils in the injectors and lines. This messes with fuel delivery.
It is because you have a hot starting problem only that your problem is surely the OVP."

I realize yours only sputters instead of not starting, but I think when it gets worse it actually can cause the starting problem.

All your questions go there because I'm f*cken tired of your dumbass spamming up the forums with your questions. That's why I'll NEVER hook you up with those AMG spacers you desperately keep PM'ing me about. Keep your word and post where all your **** belongs.

Also, if I feel like posting outside of the thread you made for my stupid questions, I will. If I have any doubt that it may be a dumb question, you have my word that it will be in that thread. Other than that, I need to nkow what is going on with my car, so quit being a fgt(I am also expecting you to counter this by refusing to get me fender spacers and I really don't care, I can get them from StarTech) Have a nice day

PLEASE for the love of God tell me how a diagnostics qustion is spam to anyone other than you, Mr. Pham. seriously, you are wasting your time typing up all these complaints about what I post. This post is legit and you know it. Also, if I feel like posting outside of the thread you made for my stupid questions, I will. If I have any doubt that it may be a dumb question, you have my word that it will be in that thread. Other than that, I need to nkow what is going on with my car, so quit being a fgt

Anything you do is ... simply stupid. Therefore, anything you post belongs in the stupid Andrew topic. So as long as your posting on MBWorld, I'm going to be sure you get NOTHING from this valuable forum until you actually "learn."P.S. hope your car breaks down.

Ok, Chris, SERIOUSLY, you need to relax. Who gives a ***** if he posts a thousand times a day without searching. As long as he puts the subject correctly in the title, we can choose to read it or not. It's a free world and you need to stop acting like a mod/post ****/child. Let him be an ignorant fgt and never learn things on his own or search on his own. HE will be the one suffering in the real world when his mom takes her teet out of his mouth.
I am tired of his posts too, but I am also quickly growing tired of reading your hate rants on every post of his. You can ignore him. I won't bring it up in detail, but you were a bit of a pest yourself when you first joined....you aren't perfect, or an MBWorld God.
