BATTERY BATTERY...Hey all. Accidentally left the trunk open for 3 days straight and battery went completely dead. Tried a battery jump-starter and wasn't strong enough to power back up, so I got jumped from my neighbors car.
I let it run for 20 minutes and took it for a spin, Right away, I noticed the car is struggling to accelerate, the engine sounds WAY louder when accelerating, and when in idle (with engine on), the car shakes/jolts every 10-15 seconds or so.
Do you think I just need a new battery or could something else have went wrong?
I just put in a new battery myself this past week and it was totally worth it. For MONTHS I was dealing with sluggish, took forever to change into gears, higher rev, louder acceleration, and jerking especially between 5-25 mph, everyone kept telling me it was because 1st gear is rough. I kept feeling it the most when pulling into my driveway thinking its going to die because i'm not giving it enough gas. I drive standards as well so it was hard to judge what the cause was.
When the issue started the dealer told me it was the spark plugs, they said they had fouled out all at the same time....They tried to show me a set of plugs that I knew weren't mine, I disagreed with them because that's what I thought the problem was and replaced them myself at home a few weeks before with non factory plugs unlike the ones they were holding. They didn't want to look any further since I refused to pay for them to change the plugs that were maybe a monthish old, after all I did it was the battery for sure. I cleaned the MAP/MAF sensors, air filter (thinking it was 'gasping' for air), changed the spark plugs, changed the coils, the final straw was the battery. 2 years ago I had hail damage to the car, and while in the shop they killed my battery because the doors were off and they had the battery connected so they would drive it in and out of the shop during the day. The told me they replaced my battery but I could clearly tell by the date on the side of the battery when I pulled it, it was not replaced. I'd bet you're issue is the same as mine was. (PS-Alternator tested fine during this whole process)
