Question about 1989 Plymouth Horizon America
My 1989 Plymouth Horizon Idels rough and the Exhaust smells rich and stinks . When I accelerate it runs like a champ. But when I try to keep it at one speed like 45 50 55 it starts Bucking and jerking very hard. So I accelerate again and its fine but by now Im almost going 70. It wont run smooth at all while trying to maintane one speed.Can you tell me what is wrong with it??
You probably found the answer to this a long time ago. But I had exactly the same problem (or at least the bucking thing, the fuel thing is something else). Apparently the torque converter on these things has a solenoid that makes them latch up at appropriate times to save you gas. If it screws up, it will do exactly what you describe. You can solve it for the time being (or forever) by just disconnecting the solenoid. Hope this helps. It cost me about seventy dollars to find this out.
