Make sure with cold start as above, tap gas pedal once to set choke (throttle up). There is an adjuster screw but if this just happened then that is not the problem. Check the operation of the linkage and make sure it is moving smoothly.

If you brought it into the shop the first thing I would do-
Check compression cold, just for grins, 215k I would like to know, then check it hot. I have seen really low compression cold and then it picks up a lot when hot. 200k is the life expectancy on the first gens. Had two here last year, 230K and 206K. Still running strong, leaking a lot of oil but still running, still had decent compression. Completely worn out inside, rotors and eccentric shaft were the only things we could have used. Apex seals were ~5 mm. The 230K was being driven between Phoenix and Tucson occasionally. He dropped it off then took the 93 FD back. It was his ,bought new in, 83 that we restored. If there was a 2003 7 he probably would have bought one. Didn't want an 8.

Sorry guys, back to issue at hand

AC on issues-
Check BAC and system, (AC related)
check Vent solenoid valve
check Air supply valve

I have been able to clean the BAC and ASV to get them to work again. On the ASV, there is a little sleeve that comes out of the solenoid, push it back in.

Cold start issues-
Nut behind the wheel and cold start procedure - above
If that is correct
Injector operation- sticky or bad flow cold - bad connector or wire (personal experience my own) broken underneath insulation. Fuel leakage
Check water thermal sensor
Fuel pump switch in AFM
Fuel pressure
Check TPS, not setting resistance readings cold

rough idle
vac leak
BAC system (AC related)
ACV - see if there is any air coming out the acv at the hose going forward
AFM
IAS
Vac switch
Fuel Pressure

At this age and mileage anyone of these could be an issue. Weird idle issues hot and cold have been linked to the ASV, VSV or BAC. Personal knowledge.
