This truck starts every time but I either have to turn it over once, stop, and then turn it over again to start, or on the first time, it will spudder weakly a little, then fire up. Once in a while
it will just turn over strong on the first try but not often.
It now has a brand new alternator, new spark plugs, a new fuel filter, and a new air filter at 144,000 miles. The plugs and filters were overdue. It starts just the same before these updates and after.
The battery only has about 7 months left on it but it shows good on 2 different testers.
Any ideas or suggestions?
As another symptom, it also seems to have slight power loss beginning at about 50 mph+ but it will go up to any speed, not too big of a deal.
Although, this may have changed with the spark plug replacement. I drove it today up to
55 mph and it did not have the loss/shudder feel at 50 and the check engine light did not
come on. Before the new plugs, the light came on almost every time I drove it at any speed. I'll have to drive it some more to see if this has really changed permanently.
