Wipers off track

diagnostic codes : P0102
this is my very first car in life and I'm 46yrs old. I bought it from an auction. I am very happy and proud of myself for finally being a car owner. please help me understand what I need to do and if I can afford to save the car.

The Car start Rumbles and will try to give it gas it dies like it's not getting enough gas but it will start up every time and I can have no power you trying to go and it will just die

the problem occurs at random intervals.i have replaced the crank sensor and the ecm .i have scanned the diagnostics and there are no codes.when the engine dies it just shuts off as it would if i turned off the ignition ,no sputtering ,or bucking as it would if were getting no fuel.it simply stops running!my next move is probably going be a new engine wiring harness.it is very hard to diagnose be cause it happens in any time frame when i first start it or after i have been driving for hours.please help i'm ready to go postal on this car!

I am told there is a 14mn nut that need to be removed

frt wheels bob, just replaced wheel bearings? was told that was problem obviously not

All of a sudden the rpm needle does not move .

The car has senenty four thousand miles on it. It has also had brake problems.

The engine tries to start then chokes out, sometimes with a backfire, I try again and the engine will start with hesitation then idling high gradually idling lower...someone please help?

my blower motor fan is only working on the first three speeds, not on high, and my hot and cold is working but not my air conditioning on the first three speeds. i have two questions, the first is my problem the switch or the resistor and the estimate to repair it. the second question is if the blower motor itself could cause this problem if replaced with a defective motor or replaced incorrectly? thank you.

the car blowen 2 head gaskets water shoots out radater but temp is under 200

I have had new hub,pads,rotors on back and new sensor on front left. The low trac light comes on and the brake padel pulses at times. Sometimes the odomoter does not function. What is the remedy?

Driving on freeway, went to pass a car, my car went down a gear to 3rd passed the car & my car never went back to 4th gear or overdrive. All other gears work good, fluid level good. Still able to drive, just runs at higher rpm, been like this for 2 days now. Service eng soon light came on about 5 miles after losing overdrive, connected ETHOS scanner, got P1870 code (transmission component slipping), cleared code, light went & stayed out, still have problem. Have 215000 miles on car, tranny rebuilt at 108000 miles. Suspect internal problem?
