ok so here's what the car is doing. It'll start but wont idle unless i give it gas but runs real bad and blowing black smoke. Now it has acted like this before,6mths. ago i took it to Alan Brown to have tranny work done and converter. Once he was done and it was time to test drive it it acted the same way . He found a bad IAC and replaced it and it ran fine. So fast forward a couple months , i ended up in an accident and took it to the body shop and had the frame straighten when i picked it up it ran fine. i got it home and shut it off to make room in my drive way when i went to start it back up and acted like i had a dead battery , i found a loose ~~~. term on the battery so i tightened up and when it started up it was running like crap. i have replaced cam sensor,battery,drained gas,replaced plugs,cleaned maf,and removed IAC and took a picture of it and sent it to alan and he said when he took the one off he replaced it was stuck open and the one in the pic was not.Also i tried putting a code reader on it but wasnt able to get a code,it did the samething to alan. It has been tuned by d.dalke and has a moates chip. Im trying to fix it before i have to take it 400miles to have Dave do it
