Was this a lot of stop and go driving, a lot of idling? If not, I’ll bet some sensor wasn’t reconnected, or the connections were swapped, as part of the engine mount replacement. Usually that would turn on the CEL though. If this happened right after the prior repair, doubt fuel injectors are the problem. As mentioned above, the coolant temp sensor is a likely culprit. But it could …

WHAT THE HOME MECHANIC NEEDS TO KNOW ABOUT O2 …

+

When no signal is received from the O2 sensor, as is the case when a cold engine is first started (or the 02 sensor fails), the computer orders a fixed (unchanging) rich fuel mixture. This is referred to as "open loop" operation because no input is used from the O2 sensor to regulate the fuel mixture. If the engine fails to go into closed loop when the O2 sensor reaches operating temperature, or drops out of closed …

support combustion. Above the UEL, the ratio of gas to oxygen is too high for the fire reaction to propagate. In other words, the mixture is "too rich" to burn. The difference in concentration between the LEL and UEL is commonly referred to as the Flammability Range. Combustible gas concentrations within the flammability range will burn or explode provided that the other conditions required in the fire …
