2008 Starts, shudders and dies

I have done all kinds of suspension work underneath the car. I replaced the coil, plugs, and wires. The ones off eBay were garbage and kept popping off, so I bought NGK‘s and put the old coil back on. Still had the issue, went and got a new MAF. Still does the same thing, runs fine when it is unplugged just idles a little high. Could I possibly need to clean the throttle position sensor?

Check your egr valve if it's done. I'm dirty.It'll prevent the car from starting and running smooth

Shot gunning is no way to fix anything. If you keep it up you'll likely stumble across and remedy the problem but you'll spend a lot of money and time getting there that you didn't need to spend.
