I started noticing power issues and electrical flickering on my dash, headlights, and any lights inside the car. the probably is getting worse. The engine is struggling with power but once I run it it gets better but then the car has shaking or jolting throughout driving. I also seem to have an issue going in and out of 1-2 gear which makes me think there is also a transmission issue possibly. I was getting error codes for a misfire in one of my cylinders and thought maybe replacing there spark plugs and ignition coil would fix the issue. I replaced all 4 and the misfire code went away and the power did get better. Now the electrical issue still remains. What's odd is when its cold outside or the engine is very cold I have very little issues. no flickering or little and much more power which makes me think it might be a short related to heat. I had the battery replaced and the alternator is testing great. (alternator is a new one put in 2021). Another problem which may be realtered is when I'm slowing down my car as its coming to a stop has a really hard shift to first gear and makes a weird noise almost like the piston in the breaks is locking the releasing.

Cars are not that simple these days and require systematic diagnosis for individual problems. The first thing to tackle is the electrical issue. You are going to have to follow wiring diagram to find the source of this issue. Judging by your question it doesn't sound like you are equipped to tackle this on your own. You're going to need an electrical shop for this. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

I dont understand the cold effecting the electrical for one. As far as a mechanic how do you know the best one to take it to since it seems to be ethical related?

The problem could turn out to be very simple or very complicated. It could be a simple as a bad connection or as complicated as an intermittent bad module. You can start off yourself with the basics. Clean and tighten the battery terminals. Check all grounds and major power connections for any loose conditions. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
