1998 318 Cold Start Problems... :/

Ok, so i decided to purchase a 98 318. The car has a problem. It seems the colder it is, the harder it is to start. Once its started and fully warmed up, you can turn it off and it'll start right back up. It just when it sits overnight on cold days. The check engine light is on. 4 codes for cylinder misfires.... which happens when i first turn it on. I've changed the spark plugs and the coolant temp sensor (DME for fuel injection)...the one right in front under cylinder 1 and 2. Any ideas? Thanks in advance.

So your saying youve changed the Camshaft sensor?. If you have go for the MAF then o2 sensor.

No i changed the coolant temp sensor. There are 2 though; the one for the gauge and the one for the cold start fuel injection (DME).

I would change the camshaft sensor as it controls injectors, as for the 4 codes you say they are all misfire, this would point to camshaft sensor.

Garage
Wouldn't a cam position sensor throw it's own code? Mine threw that code and the car still ran fine. Changed it and had the code deleted and it never came back. Always wondered if it was a fluke because nothing changed as far as performance or starting.
