Many times if the car was parked the last time overheated and also low on fuel the fuel can boil in the fuel rail and the lines the resultigair pockets before the fuel pump picks up mkes the car miss( no fuel or not enough to a few cyclinders or even the injectors leaked a little after it was shut off. both ways it'll miss when started back. It's possible you live in an area that shifts gas from winter to summer and back the winter gas in hot tempertures will do this. The check engine light can be reset with a scanner. Codes po420 or other mixture codes may appear. ( happens alot this time of year as the fuel switch over to winter gas is happening. as soon as your car ( tunes to the new forulation ) It might not do it again. The winter gas works well in cooler days but it does what you pointed out on hot days.

My emissions light is on when I first started kinda shaky last night I noticed little smoke under hood would it be OK to drive an please someone tell me what this could he


The emission light comes on when the computer detects a leak or malfunctioning part in the system. It can come on due to a loose gas cap to a disconnected hose. There a lot of things that make this light come on. IS the check engine light on/flashing? If so, you may have a misfire causing the shake. If the engine light is on, have the codes scanned to isolate the problem.

Try cleaning the Mass airflow sensor and replacing the air filter. You can buy the spray MAF sensor cleaner from any auto parts store for about $6.00, ask the parts guy how to use it.

Ford Escape started sputtering tonight and then the emissions light came on. Car had been sitting for 4.5 days. What's the deal? Safe to drive another 40 miles?


Yes, it is safe to drive.
It could be something simple like moisture on the plug wires, water in the gas tank, etc.
But there will be codes stored in the car OBDII system that will tell you more details.
A place like Autozone will read them for free.

2004 ford escape engine emission light on lunges while idleing


I have found this to be a common problem on 2001-2006 V6 Ford Escapes. In 99% of these cases the problem is the Catalytic Converter. The V6 has three in-total, one per exhaust manifold, and one after the Y connection. This third catalytic converter is the one that always gets clogged. Another clue to it's failure is a loss of power and a increase in fuel consumption. The later 2006-2008 have a redesigned exhaust system. Hope that helps.
