Why does it sound like my lifters are tapping when car gets hot then cooling mode comes on

bank 1 erased check engine light but comes right back!

Well i buy a tachometer and i dont know where i have to connect the principal wire. The wire that say me the rpm. I connect the others wires but i dont know where i have to connect that one. Help!!

The temp readout gauge works intermittently. When no reading appears, I show the same codes. Unfortunately when I have no reading and it appears as ---F, my A/C compressor will not function either. It's very hot in Phoenix. What else can I check? I am desperate.

I've replaced the bulb twice so I know it isn't that, the diagrams for both fuse boxes don't identify which fuse is for the turn signal or blinkers. The bulb actually won't turn on at all so I'm guessing it's a blown fuse, just need help identifying where the fuse is located on either fuse box

HOW TO TAKE OUT FUEL PUMP IN MY CAR

No power even to the panic box?

I had taken it to Dobbs and they replaced thermostat and compressor still same symptoms. I have always noticed a wack smell coming from the vents. But I can't keep wasting money. What is the problem?

I ran over a rock and cracked the oil pan. I replaced it with a new one. The next day drove the vehicle on a 55 mph road and was no problems. I then got on the free way and drove at 75. No problems thenstarted going on a incline and the vehicle started to hesitate. A few seconds later smoke was coming from the engine. So i coasted it and and parked. I waited a few minutes for the engine to cool down and looked under the hood there was oil leaking. I checked the dipstick and was empty. A few hours later i filled up the oil again and it kicjed over but started to sputter and the oil that was put in completely leaked out. Suggestions.

My friend recently helped me install an after market double din. He rewired everything for it to work. Now, my a/c is only blowing cold air when driving, coolant temp goes way up when on idle over 115 degrees F, my halo and LEDs on my headlights wont turn off even after the engine is off, it alarms by itself.

It also has a fuel injecter that needs replaced also told this could indicate a computer issue.
Car seems to run fine and owner said engine just turned on a few days ago. He is fixing the injectors and says this is not a big deal. Need a reliable car for my son. Anyone agree with the owner?

I was driving the other night and when i put my car in park my engine light came on. I used a obd2 scanner to find out it was a p0121 throttle code. Is this something that will cause me to fail emissions considering the engine light is on

It was working great one minute then all the sudden it won't accelerate

I have a g5 Pontiac that's a 5 speed. So I always use my e-brake. When I got in it this morning the passenger side was locked up.

I have already cleaned out the air filter taking it for a long ride but I'm also wondering if it could be the relay switch for the air flow pump or the powertrain because the car seems to be running fine it just will not pass emissions

Blower motor was replaced a year ago when it started doing this but this is the first time I noticed the wiring getting extremely hot any ideas. This happens 6 to 8 times a day while driving

It sounds like it's misfiring. It sounds like ca'tst. Ca'tst Ca'tst. It keeps going if i keep the key turned.

There is a knocking sound in my 2008 G5. Diagnostic code recommended changing the knocker sensor. Knocker sensor replaced. Knocking sound remains.

My coolant temp readout reads -----. Don't seem to hear the a/c clutch kick in when I switch on the a/c

When driving it sounds like im stuck in 2nd gear/overdrive. Icant locate an overdrive button if there is one. Now ck engine light is on.

It has happen three times so far, I would put my key and the key will not turn, I jiggle it, play with transmission shifter. After trying this a few times the will turn and engine turns over. ????

It has around 143,000 miles, recently bought from a private party owner and whenever I start in 1st gear it sputters as if I am driving a manual for the first time. I got a test for the check engine light and they said it was the Throttle Body Sensor so I went ahead and got a brand new Throttlw Body and sure enough it appeared. I can't accelerate very much, can only use around 10% of the power. I am trying other things shortly. Anything will help, thanks for listening.
