I have a 91 honda accord ex. I had the engine replaced about two months ago with a rebuilt one with 45000 miles. When I put it in reverse it goes to fast when coming out of a parking lot. I can drive it for about three miles before the engine light comes on. Then it seems as though it is getting ready to stall out when I stop at an intersection, but it automatically comes back on only to nearly stall out again. When I put it in park and pull up the safety brake it will rev up above 1500 rpm and begin to seem to stall out only to keep running. I was told by a mechanic that I need a throttle body, but Napa Autozone and the dealer told me that this part is not available off the shelf anymore. I also need to replace the muffler. When I turn the steering wheel while in park the revs will jump up, but not signifigantly high. I would appreciate any information you can give. Daniel Seaside California
You may need a throttle body replacement, or your throttle cable adjusted. The throttle cable at times, can be taut too tight, and can simply be adjusted for more travel. In regards to locating a throttle body you may need to search for a rebuild kit, or search on-line. When turning your steering wheel, it is normal to see your RPMs jump, because you are putting strain on your power steering, which in turn will put strain on your harmonic balancer.
Hope this helps!

Since the check engine light is coming on, I would take it back to the shop that installed the engine and have them take a look at it.
It may be a transmission problem, but at least you'll know if it has anything to do with the engine. I'm sure you got some sort of warranty?
