Hey everyone, took the old thread down to add some more info and realized it would've been easier to just edit my old thread.
Anyways, when starting the car up in the morning it occasionally will "jerk" when I give it some gas. When starting the car up sometimes there's a weird noise from the engine too but the car starts up fine, like a "cha cha cha" sound LMAO, don't know how to describe it. As well, sometimes when I give the car gas when the light turns green it goes for half a second, "jerks", then keeps going like nothing happened. When idling, the RPMS are at around 500rpm or a bit below 1000rpm, but there's a fair bit of vibrating when idling at a red light. I'm thinking that it might be spark plugs, but wasn't sure if I should pay for the $100 or whatever bucks and get my mechanic to do a diagnostics test on it and see if there's any other problems, like maybe MAF sensor or something. Advantages is that I'll know if anything's wrong other than spark plugs, downside is if the test really does come out saying that the spark plugs need replacing like I originally thought, I'd have wasted like a hundred bucks just for peace of mind.
I guess just not sure if I should pay for spark plugs to get changed, which I'm pretty happy to do so with my lack of knowledge/space/tools/laziness, or get the diagnostic test done and maybe it turns out the MAF sensor needs cleaning and that's all I need to do
Thanks!!
