Rough Idle (Possible cause?)
So, when I bought my car a year ago(used) it had a misfire
in cylinder 1. Got that fixed with new spark plugs. A few
months of having the car and the fuel pump went out.
Replaced that. Replaced the air filter and regular oil
changes. No check engine light. No overheating.
Still, my engine idles rough. My seat vibrates and slightly
the steering wheel when in park or at a stop light on brakes.
No weird sounds & no trouble starting the car.
It idles mostly like at the rpm shown in the picture but
occasionally, when it's really warm out, the idle will rise to a
solid 1000rpm & be completely still, like it should be at idle.
I'm having a hard time narrowing down what could be
wrong. Any ideas?
