I agree with Pyro, Don't throw money at your vehicle, complete your testIng my friend. If you pull your throttlebody, make sure you only use throttlebody cleaner on it.I'm going to order two new coils and put 4 new plugs in. I'll also go ahead and take a look at the Throttle Body as well.
Get your vehicle up to running temperature, and park on a loading dock ramp, or something otherwise similarly steep. It is difficult to purge all of the air bubbles out of a system without doing this.OK. I sprang for another 2. I'll replace all 4 coils and all 4 plugs. With almost 190,000 miles, proabably a good idea. I replaced the Valve Cover Gasket on my 2012 after my daughters 2010 failed. I had some browning on Cylinder 1 and just went ahead and replaced. I have the the pulleys I ordered that still need installed. My nephew suggested it was a cheap replace after he installed my new radiator and thermostat.
bro, let us know how it goes… I can definitely see a plugged catconverter being an issueNew Throttle Body did help performance of throttle response, but not the stall. I got all the other parts down to my nephew. Plugs were pretty rough and one broke off but he's got tools for that. The CAT he said was a little clogged and had a chunk missing out of the honey comb. He said he didn't see the debris so it's definitely bad. I'm confident now the new CAT should fix the issues as I was getting 22-23 mpg before I started with any code issues. Been running around 17-18 with all these stall issues, sometimes lower.
