So I was taking the s10 for a spin and wash last weekend, and noticed it was idling extremly rough. (shaking the vehicle side to side) after about 5-10 min running, my Service engine Soon light came on. I stopped and did some erands, and when I started it again the rough idle continued but no light 10 min later the light came on again. This happened both while cold and while at op temp?

As a reminder I did a 100k tune-up/plugs/wires/dist/etc and ran pretty good for 4-6 months (about 500 miles - its a weekender)

any ideas what is going on or do I need to take it in for a diag?

thanks

 

u never said if u changed the fuel filter as well. some people don't do this as often as it should (eithier because they find it difficult, or they're just lazy). i'm not saying you're on of those people but, if u did change the filter, try taking it out and see if the element inside has collapsed (causing a restriction). i've seen this happen with fairly new filters before, so u never know.

 

Appreciate the response 70mopar,

Yes I did change all the filters (well a service guy changed the oil ones) I change the air ones to K&N, but I will certainly pull them and check.

 

Have the codes scanned to see what they are for.

 

Well I took it to the mechanic last week, and after the check book was pulled out,

I have new injectors and a new EVO? (at intake manifold) valve.

It seems to have fixed the issues - no more warning lights on dash, and smooth idle, turns right over as well
