Hesitation when engine cold on 2000 CE

[AndrewK]

My wife has a 2000 Corolla CE, about 55K miles. Plugs and wires are fairly new, and it's had a couple of doses of Techron fuel system in the last few tanks.

She's having problems with it hesitating when the engine first starts. It idles fine, but when she steps on the gas it won't go right away.

This started a few weeks ago. Now the CEL is on and it's worse.

Once it's warmed up, all is well -- smooth as ever.

Any suggestions? I'd hate to blow big bucks on new injectors, but I can't think of what it might be. We're bringing it in to have the CEL checked, but the hesitation started before that, and I'd like to have some idea what's up.

Thanks for any suggestions!

u should always allow the engine to get up to normal operating temps before flooring the car....most cars will be in "limp" mode until the car is warmed up...

Geez, we've never warmed up a car since fuel injectors came on the scene. And the car never hesitated before (and neither does my Solara).

We're not talking about flooring it. It hesitates just pulling out from the driveway.

PS: Nice 2. Used to have an '88.
