Ok so the everyone who has modified their 94-95 Mustang has dreaded the idle surge from day one! My own personal stroker motor car has a chip and tune and STILL likes to surge a bit until it warms up. EITHER WAY, the principals are the SAME! I hate to link off of the site to do this but I haven't found a MORE thorough write up on how to solve your problems than this very site...PLUS it features pics of a 94-95 so it makes it MEGA easy, even for noobs! Click here to solve your idle problems! http://www.muscularmustangs.com/iac.php be sure to click through all the pages! the link is at the bottom of each page. Remember this! It is imparative that you do all of the steps in the above link in order! Setting the TPS Voltage and THEN setting your idle RPM will throw the TPS Voltage right back off!
