While accelerating to merge onto the highway, the check engine light came on and I could not accelerate above approximately 45 mph or 3000 rpms. I let off the gas thinking the Jeep would slow, but it didn't slow down. I was able to decelerate by braking (obviously). However, I was still unable to go faster than approximately 45 mph or 3000 rpms. I took it into the shop twice before because the check engine light came on, and I was told the oil pump was stuck on low (?) this has been an ongoing issue for the past four months. There has always been something wrong with this vehicle despite regular service maintenance visits.
