Cruise control is a separate module that was likely removed when they took the intake manifold off. It’s possible they broke something during disassembly and didn’t tell you about it. As for the power steering, you probably just have air in the system and it needs to be bled out. I would take it back and complain if I were you.
You probably have a bad ground wire somewhere so you’ll wanna track that down. From my experience, it’s usually a bad ground wire underneath the battery tray
Yes absolutely. Replace all the seals, gaskets, hoses, belts, etc. while the engine is out of the car.
Yeah you’re gonna need to do some serious electrical testing on that car. Never a good idea to install a battery backwards. You can destroy all kinds of things like the alternator, the main computer, and lots of electrical stuff. On something like that, you’re best bet is to pay a mechanic to hook up his computer and do bidirectional testing on all the electronics that way they can tell you what’s wrong rather than guessing.
Yeah that’s all normal. When the car is in the air you can spin the wheels freely because there’s no pressure to tell the traction control to kick in. now when it’s on the ground it will move back to a certain point before the internal transmission lever stops the car which is not good for the car. It’s why Eric always tells people to use their parking brakes even though a lot of people with automatic transmissions usually don’t
Yep that’s true. Just for your own sake, I would recommend replacing the torn throttle boot right away as that is likely the source of your problem. At which point, you can go ahead and clean the map sensor inside of the throttle body and see if that fixes the problem. Be sure to disconnect the negative battery cable before you unplug any of the electrical connectors.
Yep it’s bad. Time for a new catalytic converter. And you wanna replace it sooner rather than later because those altimas are notorious for sucking the internal comb part of the catalytic converters into the engine, and then you have to replace the engine. So you don’t want it to get to that point. I see that a lot on Nissans, especially the altimas.
I’m not sure on the specifics of that vehicle. Perhaps Eric might know. But I do know that a lot of times with those cars the fuel injectors get Carbon build up in them overtime and need to be cleaned. So my suggestion would be to clean those out. You can do it yourself if you have an air compressor, or you can take it to a shop and have it done. I believe Scotty Kilmer has a video on YouTube called “how to clean fuel injectors” and that shows how it’s done.
You probably need to clean out the throttle body and the map sensor on that car. A lot of times they just get dirty overtime and there’s a special cleaner you can buy and then once you take it all apart you basically just spray it in there liberally and you don’t wanna touch the map sensor itself but you can wipe down the inside of the throttle body with a rag once you spray it in there. You also wanna disconnect the negative battery cable for like 5 minutes to reset everything. That should fix the problem.
I would stay away from those if I were you. Fleet maintained means that they were owned by a company like a business agency, government, law enforcement, etc. and they can be well maintained but they are often worn out or have a side story behind them like perhaps they were in a flood or an accident that maybe you don’t know about. If you’re serious buying a car like that, I would pay a mechanic to check it out first before you buy it and he’ll tell you if it’s a good car to buy or not. As for the impala, I can tell you that some years are good some are not. I don’t know which years are more preferable than others but you would wanna do some research and find that out as well. 80k is a fair amount of miles for that car so again, proceed with caution. That’s my best advice
If you hit a pothole and you keep going through mounts like that, chances are there is some other structural damage that was done to the car. Possibly a control arm or something like that got bent. You’ll wanna take it to a good front end alignment shop, they can tell you for sure what’s wrong.
