Hey everyone
I'm new here to the club and have used the website for help many times
I got a 95 SC400
Customized by the previous owner
its has 5 spd AT and I believe a diff engine as well.
She goes 0-60 in 6.1 sec and thats not stock
I just did the front end suspension top to bottom
Tracks and rides well

I love this car
I have sone questions that I'm desperate yo hear answers for...

... I'm having idle issues, she gets rough and almost dies and/or just dies, not ever when driving unless it's low speed(20-30​​​​ mph) never at high speeds

it's got an iac delete and a floating EGR
the esv and vsv are disconnected

and idle is affecting or is affected in such a way that my needles for speed and rpm start to perform their own light show

this is my first time posting I've owned this car for less than a year and have fallen in love with her lol
I'm ordering a wide body kit and taking this monster past the heights of 700hp
(WOO!)

NEED AS MUCH 8NFO AND HELP AS POSSIBLE
THANKS A LOT

 

First of all we need to know what engine is in it.
Next i'd recommend trying to get it back to stock if you want the idle and low speed problems fixed.

 

If your instrument cluster light show coincides with the idle/running issue, I'd say its an electrical problem.

Is it random? Or does it happen during similar conditions?

Look for loose electrical connections, bad grounds...

 

port snd polish Everything I can
weight reduction at least 500-600 lbs
twin 5pb turbos for top end
blown or supercharged (not sure yet)
serious suspension
And most of all, precise gearing i might do a ford 9in in rear or tundra str8 axle
WOOO!

AND fixed pwrstrg leak/kinked line and got rid of air in system
NO MORE hick ups or dYing
gonna remove hyd fan and pump after finding pressure cracks in t Stat housing
