    Had car since August. I have service records for new spark plugs, plug wires, fuel filter, battery, that were done in 2013.

    Ive had a random lumpy idle issue that occurs every maybe 5-8 starts. Car would fire up, engine would kinda stumble and then smooth out after a split second. Then once at work I went to start it, and it cranked for about 10-15 seconds before firing up - this was back in september. Then maybe 3 weeks ago, I had an extended no crank start that last 10 seconds again but fired right up. The car has lots of power. doesn't have any issues running.

    So a few weeks ago I ordered a new FPR on ebay (yes I know). I installed it, had it in my car maybe a week, and then the car died last night in the snow storm in a parking lot parking spot. I pulled the vacuum line on the new FPR and it pissed out gas all over. Luckily I had my old FPR on me so I put it back in and it fired right up and ran perfect. I got a refund from the seller.

    Then tonight while having the old FPR, I was idling in my driveway maybe 10 minutes and the car randomly stalled. Started it back up, and drove straight over to auto zone and picked up a new fpr and put it in. Drove around for a bit, idled it a bit, and it idles at about 800 rpm's. No stalling yet.

    I've cleaned the MAF and IAC. I had a code for the MAP when I got the car and I replaced that sensor and the code went away.

    I've also had an issue that has happened maybe 3 times where I would start the car after leaving the gas station or store, and it would immediately just stall after 2-3 seconds of running but then it would fire right back up just fine. Very random.

    What year/model are you working on? Have you removed the TB and cleaned it inside/out? They will get carboned up on the backside of the butterfly valve and cause some strange issues. Cleaning the TB on my 00 GT helped a lot of issues I was having.

    What plugs are you running in it?
