morning stalls & caffeine

I've been having trouble with my 96 disco I. It will generally stall, yet only in the morning, and--get this--only when I'm craving caffeine.

During a recent service, we cleaned the valves and replaced the hoses on much of the engine. And when I say "we," I really mean my mechanic in San Diego named Behr. Anyway, the valves were sticky, but not anymore. Yet we still have the morning stalls.
I use quality Chevron mid-grade with that good Techron stuff, so I don't think this is a fuel issue. Behr says it might be my idle motor, but I'd love a second opinion.
But when I think about it, I'm wondering if my truck stalls has something to do with my body's caffeine level.

Read this and see if this makes sense.
In the morning, I wake up and find that my body is craving caffeine.
I go outside and start the disco.
I drive down the street, and the car stalls when I slow down to make a turn.
I restart, and I smile and wave to the person in the vehicle behind me.
I have to put the vehicle into neutral on subsequent turns, and rev the engine to keep it from stalling.
A few more "neutrals" and revved engines, and I coast into the parking spot at Starbucks, yanking on my steering wheel as the truck once again stalled and leaving me with no power steering.
Then I walk to the register and order a grande cup of black coffee.
The woman at the counter will then ask if I want room for cream.
I then remind her that I ordered black coffee, which means I don't want any room for cream. And I smile, so I don't appear to be an ass.
Then she laughs, and says "Oh, yeah. You said black."
I thank her and drink my morning cup.
I look outside at the sun hitting my beautiful 96 Land Rover Discovery, and I swear I can hear music. Maybe it's the speakers above me in the coffee shop. But I like to think it's more than that.

Then I go back to my truck, restart and no more stalls.
In fact, it runs just great for the rest of the day.
Then in the evening, I go to sleep.
My body has spent the day releasing pretty high levels of caffeine into the Oceanside City sewer system. My wife says I twitch a little, no doubt from my caffeine intake during the day.
And my Disco is outside in the driveway, getting ready to stall.

It's curiuous to me that the truck only stalls when I'm craving caffeine. I haven't tried checking my OBD to see if it registers lower than normal caffeine levels in the driver. But maybe this is the reason. Makes logical sense to me.

Or maybe you have some other ideas.

Thanks for reading this. I appreciate your help.
If you're ever in Oceanside, maybe I'll see you at the College Avenue Starbucks.

Adios,

No ideas, other than the fact that Rover owners have a strong connection with their vehicles.
Good story though...

the long post is, i must admit, as poetic as a story about a disco stalling can get but is a bit short on details. How long has this been happening? did you fix or alter anything immeadiatley before it started happening?When you start it up in the mornign how does it run immeadiately after start up? does it stutter or stumble at all? or does it start up and idles nicely at around 700 rpms? when you turn the ignition half way on to the accessory on position do you hear the fuel pump kick on? does it (the fuel pump) gurggle or make any strange stuttering noises? Also in the morning after you turn the ignition to accesory on position and the fule pump kicks on can you hear the fuel pressure raise until it makes that clicking noise after the pump shuts off? have you changed the fuel filter since you have had it?

also let me suggest that you pony up that extra 10 cents a gallon and go for the premium grade gas. its gonna hurt you in the wallet eaiter way when you do a fill up. My guess is that since you have the rover and seem to be quit fond of it that your main focus of automobiles choice wasn't economy. So put the good stuff in and then you will know your treating it as best you can with the gas you buy.

I see thast you live in socal and gas aint cheap there but be happy you are not in the SF bay area like i am. premium gas cost me 2.45/gallon last friday. to fill the tank it cost me over 50 bucks. Mobil screwed me and i didn't even get a kiss.

your mechainc mentioned the stepper motor: have you pullled it off and cleaned it? it wouldn't take long to do. i'd go ahead and do it.

for me it sounds like some sort of fuel pressure issue. that could account for it only happening in the morning since over night the fuel pressure will drop.

these are all just my 2 cents, but no one else has offered up any ideas so i thought id throw my hat in.

check your fuel pressure

suspect areas for poor morning starts:
fuel pressure regulator
injector leaking down
dirty stepper motor
coolant temp sensor

check your fuel pressure first with a pressure gauge first if pressure drops, check injectors for leak down, it all injectors seal roperly then the pressure regulator is faulty.

it pressures are good check stepper motor.

when was the last time the fuel filter was changed?

never lived in oceanside, but use to surf there quite a bit!!!

I'd hook up OBD-2 logger and record what is happening just before it stalls.

BTW, I have complete faith in Behr - he's never done anything wrong on my rovers, and his advice is most often right on the money. I buy my parts from him as well.

$2.45/gal in SF? The closest gas station to my house hasn't gone under $2.55 since last December. I believe it was $2.59 this morning.

Here in Leucadia we don't have that problem.
Our discos just motor along.
You need to move south my man.

gonna look into this

Thanks for your words, guys. I really appreciate you and your thoughtful input.

Yeah, I really like Behr. And would recommend him to anyone. Solid mechanic, and very fair.

I'll look into your recommendations.
Thanks, guys.
