Got an oil change, left with a check engine light
I brought my 2006 Toyota RAV4 to get an oil change(local tire shop that does oil changes), and when thr brought my keys they asked if I’d noticed any rough driving before, I said that the car has had a slightly rough idle for over 5 years now that 3 different shops have looked at and found no concerns about, but nothing too bad.
They basically said “alright, let me go check some things.” Then five or so minutes later they brought out my key and the receipt so I figured all was well.
Well, I get in my car and the check engine light was on, (as well as VSC and traction) so I bring it back in and basically get “well you can drive it to see if the lights go off or you can leave it here and we can check when we get time”
I had to do errands so I said I’d drive it down the street then back home, if lights still on I’d bring it back.
Lights were on, brought it back, they read the codes and they were saying all four cylinders were misfiring (I regret to say I didn’t get the actual codes).
They said they can’t do the fix there, that id need to take it to a mechanic shop. I got home and did some googling and saw maybe they’d knocked the MAF sensor off, but it wasn’t.
HOWEVER, I noticed this tube (2nd pic) was completely disconnected, so I plugged it back in and started my car again, lights still on. I even drove it slowly around the block but lights are still on. Do you think it just needs time for the codes to run through or should I take it in? I have a 3hr drive in 2 days..
