    96-2D-Hoe, Thanks for your comments and advice. I will check the grounds and I've been planning on performing a Big-3 upgrade so this could be good motivation to proceed. I'll let you know my results. I'm pretty certain I attached the fuel pump ground but will check this out as well.

    Great and Terrible Parts Vendors

    DON’T BUY FROM PARTS GEEK! I paid $540 for parts which were all incorrect. After 6 calls to 5 extremely incompetent “customer service” people and sending multiple messages they left me $199 short as they just decided to keep my money, with no response. Sent from my iPhone using Tapatalk

    I've replaced the IAC. I'll look into the TPS and vacuum leaks, which I'm not looking forward to. I will employ a scanner.
