Rough start

924 Views 4 Replies 3 Participants Last post by  Nate
When I start my car after its been off for a while (4 hours to overnight) it idles very rough almost stalling. I'm sporting a new Alternator, new plugs, wires, battery, rotor, cap fuel filter, air filter. Is it my cold start valve or this OVP that I hear a lot about. Once the car is warmed up it idles smoothly. I have 136K miles on a 1991 2.6, is it wise to change this parts preventatively, I wish I had done that with my rotor/dist cap.<br> <br> <br> thanks<br> <br> ssb

mine starts the same way....

I have almost the same exact problem with my 190E 2.6L. Though i replaced the wireing and had the battery checked (which was just fine) the engine still idles roughly and mainly takes a while to start. Having to turn many times before a spark is made. The plugs were also replaced and a tune up resulted in no change in condition. Somone once mentioned to me that the fuel injectors may have to be cleaned or replaced, haven't had the time to check into that, perhaps it may be of value for you to know.

First steps would be to run fuel treatment through it and see if that changes anything, that should clear up clogged injector problems. Then from there try the cold start valve which I am betting is what's wrong.

Nate, i've tried fuel injector cleaner though, many times, i also keep a steady oil change going on too. What is the "cold start valve" that you were saying?
