Trouble starting after a few stops...

Trouble starting after a few stops...
My 01 Cls Auto runs great until I make a few stops and let the car sit between 5 minutes and 45 minutes. It turns over fine but bucks and stumbles and requires some back and forth with the throttle to get it to 3 grand or so and let it idle there for 15 seconds until the idle is almost back to normal.
The mechanic I use (now used to use) claims I have to undo the throttle body bypass that I have had on since May. He claims that all of you out there in the Acurazine community don't know what you are doing. Having utilized this site for 5 years it is obvious to me that some of the posters to this site have forgotten more than this guy will ever know.
I have read about a fuel pump relay under the dash and wonder if that could be the culprit. Hate to take it to the stealership but need to address this matter

i'm not sure exactly what the problem might be, but doubt its the fuel pump relay because that only turns the fuel pump on. if it was the relay then u'd have trouble starting, not idling
might have something to do with the fuel line, injectors, etc.

Plugs and air filter are good? No check engine lights?

I cleaned the throttle body when I did the coolant bypass. The car screams when I open it up and runs fine. The only issue is when it sits for a short time after several trips.
It has to be heat soak related......

Could it be related to clogged Egr ports in the intake manifold or an inproperly installed upper intake manifold gasket?
I guess there would be egr codes if it was egr related.
Just saying, because of the recent headgasket surgery.
You may want to change out those 'Pulstar Plugs' in your list of mods for proper OEM plugs. Sometimes these engines can be particular in that regard.
Good luck!

Thanks to all for your suggestions. I had it out at multiple stops and more than 5 minutes and less than an hour cool down and it is difficult to induce a level idle.
This issue was prevalent before and after the head gasket issue. The thief who did the work on the gasket and wanted me to undo the TB bypass mentioned something about an idle sensor or something.

My cl is doing the exact same thing putters and then dies out, turns over and then dies out. i have to fire it up and then rev the gas finally i have to feather it down from 4000 rpm and it finally starts to idle right. hope the shop gave you a solution i thought it might be a dirty fuel filter? but have no idea and would love to now before i take the fuel tank out
thanks
thanks

Petie....
Does your car accelerate smoothly otherwise ?? Mine only has issues when it sits for a bit ( 10 to 25 minutes after shut down when fuly warmed up). My CL is going back to the stealership next week where I will replicate the problem for their mechanics and ascertain what the issue is.
Gentelmen I will advise.....

Ya... the car starts smoothly when the engine is cold and runs smoothly otherwise the only time it has a starting problem is when it has ran for a while and then i stop and let it sit for 15-30 min then it doesn't want to start and putters out. i think it might be the fuel pump relay or i have heard about these cars having a crapped out fuel sensor at the ecu... i have a unichip which i plugged in after this problem started to occur and so far it has over rid the original ecu and problem hasn't come back... for now i am running it with the chip and no issues but i am thinking eventually the relay or ecu have to be switched out... any thoughts????

Simon suggested it could be the TPS or a vacuum leak in the manifold.
The stealersip told me it is not the fuel pump relay although I had the same problem when the fuel pump started to go a couple of years ago.
Back to RIck Case Acura next week...

Maybe before you replace the fuel injection main relay under the dash, try cleaning up the throttle body with a cleaner. Specifically that rectangular hole at the bottom of the TB mouth. It might just be a carbon/dirt build up wc you can suck out with a vacuum...and you dont want the dealer doing this and charging you lots.

I was and still am having the same issue. I had a automotive store run some tests and they actually pointed to my alternator. My car eventually had trouble turning over after a few months of this.
Apparently the car wasn't idling at the right level and it continued to drain my new battery.
Unfortunately, I decided to replace my old alternator with a used one I found for cheap on eBay. Luckily it worked without fail for a few months but now I'm having trouble after a few stops again.
Doesn't matter if it's freezing cold or burning hot, the car starts right up the first time and idles perfectly. But after a few stops at stores and getting gas, it stumbles and fumbles until it dies. If it doesn't die, it sputters until I've tethered the gas enough for it to stop.
I'm just over 100,000 so I'm going to get the timing belt and water pump replaced any way. Might just go ahead and buy a new alternator as well.

Actually sorry didn't read the thread properly what I have experienced that has happened with every honda/acura i have owned is once in a while when I am running errands (stopping and restarting)and I go to turn the car over it hesitates and doesn't want to start...

Mainly on the 4 cylinders Hon/Acuras not so much on my CL. Never made a big issue of it just because it is very common not only with my past vehicles but also friends cars. Its also something that happens very rare. It might be even excess fuel in the lines when shutting the car of maybe just letting the car idle before shutting it down for 10-20 sec will help.

Well. My CL has been sitting still for the last month. I have somebody coming over to check it as it won't start unless I jump it.
He's going to change the timing belt and water pump for me. Luckily he's throwing in a free diagnostic too. I'll let guys know if he finds anything.

Fixed mine several months ago be repairing the ground wire under the throttle body. It was barely there. Checked and repaired a couple of others also. Not a problem since.
Won't hurt to check this before your mechanic either finds it or keeps missing it and say it waqs something else.
Good Luck.
