2003 Santa Fe 2.7L V6
I began having "soft misfires" just felt like hesitations about 4 weeks ago.
I brought it in to have it looked at and was charged $103.95 for diagnostics.
i was told there were no codes to pull but they would inspect the intake for more money.
I lost my job at that time and decided to continue driving it.
A week later I drove about 25 miles and the "soft misfires" turned into hard jerking and lurching combined with huge power loss, followed by and electrical / burning rubber smell.
At this time the engine light came on and i brought it to a different shop. The code (I can not recall the code itself) came back as a misfire cylinder 3. The mechanic recommended a new coil pack at about $380. He replaced the coil pack and on the way home it was back to the "soft misfire" I thought possibly the plugs were bad (last replaced about 40k miles ago)
Considering the newly lost job, I decided to have my roommate help me with the plugs and radiator to help save me money. He was not able to do that until yesterday.
Between the new coil pack and yesterday the hard misfires happened again. Checked the code again and got the same error as before. The hot electrical melting smell came back.
Today 6 hours at the shop, and a second coil pack new wires, tested fuel injectors and it is still misfiring. he did find a loose boot on 3 but issue till happening after he replaced it. There was a mouse nest under the intake plenum, wires inspected no damage seen. He says is acting like a vacuum problem. I am unemployed now for a month and have sunk almost a grand into this issue with 126,000 miles. The mechanic said he is out of ideas (huh???)
9 months ago I had the car in for stalling and rough idling, same code PO303 they found the coil boot was not properly seated. Car ran fine until a month or so ago.
I seriously have no more resources to put into replacing parts that are not fixing the problem, nor am I in a position to get a replacement car. I am the second owner all work before I bought the car was under the dealer warranty.
Oh they did check the CAT last week when they did the coil pack. I will ask and make sure he checked the pre-CATs as well. He only showed my the post-CAT and it just occurred to me I didn't ask.
Any suggestions? I am seriously ready to park it in a bad neighborhood with the keys in it .....
