:roll: Well i've been on this site for a little while now and been reading up lots on various possibilities as to why my truck runs rough when it's cold,gets better when its warm but not 100%.
i have tested the following and all came up good,
map sensor - tested within except specs
coolant temp sensor - right where it should be
egr solenoid - tested good
tps sensor - was a little off but move it around and come up with the proper specs,good now
so all these sensor were tested good.
tested the o2 sensor was a little low, probably could use to be replaced but that wouldn't cause my issues,
the only thing i haven't fully tested is the egr valve but it seems to be working fine,plunger moves freely and truck almost stalls when i move the valve in and out. vacuum is getting to it, no problem there.
I'm starting to think that the timng chain could use to be replaced, truck has 296,000km on it and i have no clue if it's ever been done, plus sounds a little noisy in that area when i got my head under the truck. could be possible reason the truck has some issues, timing could be way out of whack and needs to be fixed.
Any insight and help into resolving this problem is greatly appreciated!!!
Thanx in advance!!!
