Engine Rough Idle Problems

[Turbo 5.0]

I have recently turbod my 5.0 89 foxbody it ran good up until I put the turbo on it will idle fine for about 10 seconds then die. Could it be electrical? I need some info because it's driving me crazy also you can put it in reverse and run as fast as you want but put it in 1st and it will choke up and die.!!!

You guys with idle/stall problems could save a lot of time chasing your tails if you would go through the Surging Idle Checklist. Over 50 different people contributed information to it. The first two posts have all the fixes, and steps through the how to find and fix your idle problems without spending a lot of time and money. It includes how to dump the computer codes quickly and simply as one of the first steps. I continue to update it as more people post fixes or ask questions. You can post questions to that sticky and have your name and idle problem recognized. The guys with original problems and fixes get their posts added to the main fix.

It's free, I don't get anything for the use of it except knowing I helped a fellow Mustang enthusiast with his car. At last check, it had more than 200,000 hits, which indicates it does help fix idle problems quickly and inexpensively.

Turbo?

ok seriously.. did you upgrade the

• injectors
• fuel pump
• MAF
• Throttle body
• spark plugs- colder and smaller gap

Did you get a tune, adjust the fuel and/or timing/spark curve, know the a/f ratio
Check for vacuum, exhaust leaks

I thought all turbo kits came with a free set of jack stands these days.....
