Hello I'm Rick from just answer sorry to hear about your Santa Fe issues, if you see a phone call request you may choose to ignore that unless you would prefer a phone call, so it is misfiring at idle?

I just had my car water pump and timing belt done today as the water pump was linking and now that I had that done. My car is idling hard. Scanned my car and now I'm have misfires P0303 P0301 and P300. What is the cause of this

Unfortunately it sounds like the timing must be off by a tooth or so,as long as the plug wires are correct and there is no vacuum leaksThe p0300 and any other P0301 302 303 etc ...would indicate cylinder misfires

I know that. I had them before and I had to get the spark plugs and coils changed last yearThe mechanic that I went to today is closed until Monday. Would it be ok to drive to work and bring it to him to him after work

It is possible by disturbing the coils, that one of them may have failed again but seeing as you just had the timing belt service done it seems to me like it would be off a toothIf it is not misfiring that bad and it's not at a lot of miles to drive back and forth I would say you would be okay and if the mechanic is honest he will take care of it
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
It sounds like the impeller shaft inside the water pump has been bent or broken. If this were the case the noise would exist when the engine was cold, then when warmed up and coolant starts to pass through the...
Sounds like you might have an electrical issue. If all 4 wires on the relay had power, there is something wrong with the wiring. The relay wires should have ground on two wires, power on one wire and switched power...
Color doesn't always matter. You might decide to service the transmission. I would say change the filter and change the fluid and see what happens. You might add a quart of Lucas transmission additive into the mix and then drive...
Hello. If the coolant only leaks when the engine is running, then it is typically a failing water pump (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-water-pump). This is the most common thing to leak under these conditions. The water pump should be checked for signs of...
What you should do is spray the screw with some soapy water to see if you see any air bubbles indicating a leak. If you do not see a leak then try and move the screw side to side to...
Hi there. The Exhaust Gas Recirculation (EGR) valve may be not designed for the emissions requirements for U.S. standards. If the EGR is pulling from cylinder number 4 and after replacing the EGR and the computer detects a misfire, then...
You should first identify if the vehicle has California emissions or not. The difference is one will have a mass air sensor in the air cleaner and the other will have a MAP sensor mounted on the a/c evaporator case...
Hi there. Check the fuel pressure on the fuel rail and see if there is at least 30 psi. If the fuel pressure is low, then either the fuel filter is plugged or the fuel pump is not producing enough...
The cost to replace the engine may exceed the value of the vehicle. It will cost less to replace the engine with a used one versus overhauling the existing engine.
