Have to give a 2nd try to start car, 2005 CE Canada - Toyota Nation Forum : Toyota Car and Truck Forums

Hi there, I have a 2005 Corolla CE Standard, has almost 130K km on it. Sometimes when I try to start the car, I turn the key, the engine revs for about 2 or 3 seconds, but it does not start! Then I have to give it another try, and engine revs again for 2 or 3 seconds then the car starts...
It usually happens when I turn off the car and let it sit there for 5-30 minutes, and come back start the car again. When the car is cold or has been sitting there for a longer time (like 60+ minutes), the engine start right away, with no problem. Any ideas why it is like that?? Is this a big deal??
P.S. I did have engine light problem in the winter (Canada), when it's warm, the light went off itself, so it's a Intake Manifold Gasket leak problem. Does this have anything to do with what i wrote above??
Thanks a lot for any help!!

Yes, you leaky intake gasket is allowing heat soaking to occur. Fix that and that will solve your problem.

Thanks for your quick reply Mike, is it possible to replace the gasket without removing the whole intake parts?? Thanks

You do have to remove the intake and throttle body. Attached is the TSB for your problem, insist you get the update part number for the gasket, it is only $8 and you will need to get a new throttle body gasket, as you cannot reuse it. The tsb goes step by step for the intake gasket replacement. You do not have to remove the coolant lines, just remove the throttle body from the intake manifold when car is cold. It should only take 1 hr if you know what your are doing, or you could print out the TSB, get the 2 gaskets, and give them all to your local mechanic. The stealership can obviously do it, but it is pricey.

I would also check your throttle body for carbon build up. It might be time to clean it out.

Thanks Dorman!
How do I do this? When remove the gasket? Or just that kind of stuff you put in gas tank when getting gas? Thanks again.

Mike, could you please explain to me how soaking heat could stop the engine to start? Wanna learn about this.

And, is it a serious thing if it doesn't get fixed? It happened again today, btw

When you shut off your car after a drive, the trapped heat from the engine bay travels into your engine through the leaky intake gasket and causes the stumble. Since this only happens when after you drive, that indicates to me that it is heat soak. To see if my idea is correct, carefully spray throttle body cleaner all around the intake manifold gasket area after a cold start and listen if the engines revs, it may be helpful to have someone in the car looking at the tach to see if the needle goes up. If it revs/increases when you spray, your leak is causing the stumble and the heat soak. I would not call it serious, but if the CEL comes back on and you happen to have inspection, you will not pass with the light on and the rev hunting in the winter is not the best for the engine. It would be wise to have it changed on your time. Would you do the work yourself or take it to a local mechanic? It only says one hr of labor, should cost under $100 including the 2 gaskets.

To clean the throttle body, just spray some throttle body cleaner in the throttle body when the car is off. You will need someone or something to hold down the gas pedal to open the butterfly valve with the key in the on position.

Just remove the thottle body and clean the body with designated throttle body cleaner, I would use something soft (a rag) to scrub the inside of the throttle body.
