There might be a problem with the MAF connector or wiring. Also, the replacement sensor could be bad. If you don't have a scan tool you can disconnect the negative battery cable to reset the ECM, then see if the SES light comes back on. If so, what DTC's are showing?

For the idle and stalling problem, the TPS might need adjustment. It should be .54v at idle then progress to +4.00v at WOT. Or the problem could be a vacuum leak. Did you reset the 'minimun air setting' when you changed the IAC?
