Tell me the symptoms of the map sensor going bad?

I've had a few people to tell me that my map sensor may be bad but i put a code reader on it and it showed up ignition control module but i changed that and ran some fuel system cleaner through it and my truck still does alot better now, i can drive it for an hour and it doesn't start shaking and missing horribly now but the engine speed lopes when its idling or you hold it at a constant speed in park, i think this started after i got a guy to clean my throttle body out for me, could that have messed anything up?

Should I get a Challenger or f150?

I'm very torn between a 2015 challenger RT 5.7 hemi stick shift, Or a 2015 Ford F-150 XLT.

I love the speed, muscle and the fun of a car and going fast 40mph rolls racing.

But I also love trucks lifting them. They looking tough and just the feeling of driving a truck.

Very hard decision for me.

And yeah I know I should answer myself and go by what I want. But it's a hard choice for
Me. Just wondering what you guys think.

Challenger or f150.

NOTE yes I will go buy what I want in the end, even if Everone said truck… Or challenger etc etc. Just want a opinion thanks.

Is my vehicle at risk of CO poisoning?

I have a 2002 Ford F150. The exhaust sounds terrible and I've been told that the right manifold needs fixing. Is my vehicle at risk of CO building up in it if I have all the windows up? This concerns me a bit as we're entering winter and obviously I can't have the windows down. It's an old truck with lots of rust so I'm concerned that exhaust could leak into the vehicle. Any thoughts would be helpful. Thanks.

Added (1). @Keith, how is it that CO can build up in a vehicle and kill someone. I mean, aside from the obvious stupidity of hooking a hose to the tailpipe. I'm talking about unknowingly. I've read some news articles about this happening to people and I just want to make sure my vehicle isn't at risk of this.

Reliability of a 1990 ford f150?

I wrecked my old car and am buying a new car at the end of December when my house is done being built and my credit opens up. I needed a car to get to work for 2 months so i bought a 1990 f150 for $1000 to get me threw 2 months, so far it has driven fine, if i sit still for too long it starts to stutter and sometimes stalls in reverse if i leave it sitting, i was wondering what the chances are of it making it threw 2 months

Which pick up truck is better?

The Ford F-150 SuperCrew Cab or the GMC Sierra 1500 Crew Cab. Based on its appearance, safety, features, benefits, price, etc.

Ford F-150 1992, start to smell gas, then stalls at intersection?

So I filled up my truck with gas yesterday; I started to smell a lot of gas. Figured I would bring it to the shop later. This morning, I was turning right at an intersection and the truck stalled. It sounded like it was trying to receive gas. After a couple times and receiving it I got it started. So I pulled over and tried the rear tank to see if it made a difference. It started to stutter, so I switched it to the front tank. Now it's running fine. Any ideas of what's going on?

What is the biggest size tires that I can fit onto my 2015 Ford F-150 18 wheels?

I apologize if this may be a common question on forums, but I'm new to trucks and the answers vary so widely.
I own a 2015 Ford F-150 XLT SuperCrew, and I was hoping to get larger all-terrain tires. I was planning on either getting the NITTO Terra Grappler G2s or the Boyfriend Goodrich KO2s. I currently have a leveling kit on my truck, so that should give me a bit more clearance on going up a few tire sizes. I was told by some F-150 company workers and they said that the biggest size would be 285/60-18. Is this true? Also, could I get away with going up to 285/65-18's or would that cause rubbing?

Lastly, which of the two brands of tires would you recommend for overall quality?

Thanks in advance!

Added (1). I came across suggestions of getting 35x12.5-18 tire. Would this size tire work, or would that rub? If it were to rub, how much trimming would need to be done for it to fit properly?
