I'm not the most car savvy guy in the world, but here we go.
Recently purchased this 94 Accord, automatic tranny 140k miles. Died on the highway a few weeks ago; speed dropped out and I could only limp it down the road. I have driven it to a few different shops and back to my place and it goes like this: starts out driving fine, but after a while it starts losing speed. Then it "catches" and speeds up again. Does this continuously. I can get it to drive between 5-40mph, but sometimes It comes to a complete stop not matter how much juice I give it. I noticed if I turn the car off and turn it back on again, it kind of "resets" and I can drive normally again at least for a few minutes. The longer I drive it, the worse it gets.
What I've Done:
Took it to Pep Boys (I know, but it was close), and they told me that I needed to purchase the "whole air tub" because mine was old and worn, and that was affecting the air mixing with the gas. The guy said he couldn't find the part, or give me the exact name, and when he called back he said what I needed to order was the air cleaner assembly. Had to be special ordered from Honda Dealer, so I went to pick up my car and drive it home until I got the part, but as they were getting it ready I noticed what they had actually taken out was the tube that sits in front of the air filter housing (no idea what its called, see below), and is not part of the assembly he told me to order. I held off on ordering anything, mostly because he couldn't tell me the name of the part.
I did the carburetor cleaner test on the air cleaner assembly, where you spray the cleaner on it and wait for the engine to react, when it reacts you've found your leak/hole. I sprayed the whole assembly and got no reaction, but when I sprayed it down the tube in front of the filter the engine absolutely did react.
Frustrated, I took the car to an import repair shop with an excellent reputation, and they looked at it for a very short amount of time and told me I actually needed the tranny rebuilt. To their credit, they said they didn't even want to do it and recommended I call around because a tranny shop would give me a much better price. But I'm hesitant about their assessment.
I've read online that when the MAP sensor is ready to go, it can cause the car to slip, jerk, and even come to a stop as if the tranny is going out. So I ordered one for $10 just in case.
Any suggestions as to what is wrong would be very welcome!
Here's a pic of the tube I'm guessing the mechanic wanted me to get but couldn't find or tell me the name of. Said I needed the upper and lower part of it.
