Sounds like you have a bad ECM

Here is a thread that has a lot of info on bad ECM and repars...

The thread says 2.6 but it is the same issue with the 2.2



I would pull the ECM out and open it up to see if there are any leaking capacitors, its almost a guarantee that there will be corrosion from capacitor acid.

I have a 92 2.2 EFI also. I'm pretty sure my hesitation when its cold is from the ECM too. Haven't checked though, take some pics of it and Good luck!
