ENGINE STUTTERS WHEN STARTED WARM

1999 Toyota Corolla • 60,000 miles

I have a 1999 Corolla with about 60,000 miles on it. The engine starts fine when it is cold. But if I start the car the when the engine is warm, the engine "stutters" for a split second and results in a very short "shuddering" movement. Once started, the car runs fine. This has been happening for about six weeks.

My old mechanic just moved out of the area and I just started going to a new garage. This mechanic said a tune up and a fuel system service are needed. I can understand a tune up is likely needed, but I cannot see how a fuel system service is necessary at this point. I am inclined to do the tune up first and assess the results. What do you think? I will be pleased if you can see less expansive ways to get it fixed!

If the idling speed is low at operating temperature, I would suggest having the throttle body and IAC cleaned first.

Fuel system service is not necessary now and if a tune-up is due, that should be done.
