i have a 91 rs, 305 tbi. occasionally after ive shut the car off for a few minutes, such as when i fill it at the gas station, i will start it and it will act like its flooded, i have to run it up to around 3000 rpm to get it to clear up. sometimes it dies and i have to hold the accelerator to the floor to get it to start. any suggestions would be appreciated.

 

is thier any error codes? check your timing see if it set wrong
