Thumbs down 2001 4Runner dying computer?

I took my 4Runner over to my mechanic today because it has been randomly giving me problems with acceleration. When I push the pedal down from a stop light or turning sometimes it just sits there for 5-10 seconds before actually accelerating. The techs could not reproduce the issue (because it's so random) and told me it's most likely a dying computer, which would cost me $2,300 to have a new one installed. No CEL.

Has anyone here had this issue before? If so, are there other things to try before replacing the computer?

Thanks in advance,

There's so much else that could cause hesitation. When was the last tune up? Is the throttle by wire system working properly ( I think 2001 and newer had it) You'd need to hook up a scanner or something like an ultra gauge to watch the throttle position, engine load, a/f read out, so much else

i have a 2003 tacoma do that a couple of months ago. it was throttle by wire. the throttle body was bad. i highly douby your computer is bad and 2300 dollars is a rip off for a computer. i just bought a used computer for my 2000 tacoma for $100. they need to get it in condition with the scan tool hooked up and monitor the throttle position sensor when it happens even if they need to keep it for a day or two.

After a few months of dicking around with everything from vacuum hoses to wiring harness connections the issue was too simple:

Clean the butterfly valve. Yeah... mine was a little dirty:

No more issues!

The ECM is covered under the toyotas customer support program. It went into effect 8\7\13 and ends 8\7\16. I had my throttle body replaced at no charge. Read my post about my p1126 cel. It covers the throttle body, ECM, TPS, and 2 other things I cant remember. Unlimited milage.
