Van was working fine, had a dead battery and someone jumped the battery for us. After that experiencing weird behaviors which started off as buck/jerking at 35,000 RPM, then you let your foot off the peddle and back on then when the RPM's drop a little you re-apply the gas and it goes, but now we are experiencing extremely poor gas mileage, and the van is sluggish to take off from a dead stop or actually to just accelerate.
