Not sure why air fuel and mass air sensors replaced,did you have codes for them?Make sure to use oem parts for best results.Also when you get gas never keep adding fuel after it shuts off the pump.The truck OVRS (on board vapor recovery system) is made for vapors only and you can force raw gas in to the evap. canister,this will give you a rich runnning condition that is more noticeable after warm up.
The code description is not right,You will need to have it checked,then let us know the code number ie;P0302 or something to that effect.
If your gas cap is tight and you dont have a hose off the evap purge valve from a quick lube checking your air filter then it is most likely a bad air fuel ratio sensor,These are common on these cars.But you do need to have the code pulled with a scan tool.
That is the wrong transmission fluid,You need to drain it and fill it with Toyota trans. fluid WS. and have some one pull the fault code from the cars Computer.We are not to far from you and we do have the Toyota Techstream to do code checking and softwear updating for your truck.
If you could get some one to listen back at the tank and just cycle the key on and see if you can here the pump come on,You could take off the gas cap and carefully put a hose in the filler neck and listen for the pump.It should come on for a few seconds and then shut off till you cycle the key again or crank the engine.Crank ssnsors are also common on these motors,a scope or scan tool watching for RPM would help.Crank sensor should throw a code and engine light,the fuel pump will not.
RPO Stands for Regular Production Options, It is located in your glove box on a label there will be letters and numbers like C5H FE3 and so on.There may be 2or3 options for your brakes,ask the parts house what the posible ones are and look on that label to see if it is listed,,If it is then you have that option with that truck.
The options are to fix the car or spend $150.00 on emission related repairs and get a waiver.I would recommend a shop with Hyundai oem tooling to check for softwear updates also. We use the Hyundai GDS with 2011 softwear.Call us if you need an appointment.215-646-9150
I just had a 1995 S500 in with both lights on,It was seperate problems.But maybe a pattern for this model and year.
I would start with pulling the trouble code.On Caddilacs you can jump the a and b terminals with the key on and count the flashes(code 12 is normal it will show 3 times and then the fault code.Or in the climate control hold the off and warmer buttons in with the key on and it will self check and give you fault codes.This is the first step.The trace out the fault code if it seems related to your problem.
If the noise was not there before I would say it is belt tension related.Could be an idler pully bearing.The fact that it cycles makes me think the air conditon could also be playing a part in it.We are not to far from you,if you would like,we could check it.
