Hey all, I'm new to this forum & new to mustangs honestly, been part of the Thirdgen world for awhile & decided to go a different route....anyway I bought a 1990 lx coupe 5.0 aod car....I bought it knowing itd be a project....so let's get started on my problems.....first off....at WOT the trans won't shift out of first....it just bounces off 4800-5000...but shift fine at any other time...shifts really hard too.......second...the air bag has been deployed...but the car is straight & even the original hood is perfect...so where are the sensors that actually deploy the bag? & where do you get an airbag, & wheel & how do you get the air bag light to atop blinking after that.....last....the car won't idle on a cold start...I have to hold it at 1000-1500 for about 3 minutes then she will idle but even then the idle kind of bounces between 600-800...I've only replaced the TPS & MAF car has bbk headers, trickflow upper & lower intake and a cai...that's it.
