Shifting to park issues, other dying issues
So I got this car about 2 months ago. It’s got cam, stall, gears everything was done before I bought it. Few days after I bought it, I was in reverse backing out, and it died. Started right back up, had a check engine code evap system. Took it to a local tuner, had him tune everything, changed O2 sensors, then everything seemed good.
Then a few days later, after driving for 30+ minutes, the car would idle search and then die, only when in park or neutral. Once the car is warmed, been driven for 15-20 mins, if I park let’s say at a gas station, leave the car running for 5 mins, it will search and die. If I put into gear while searching, it will catch itself and not die. It’s never died while in drive or reverse since the tune.
New issues just came up today. After driving for a few hours, running errands what not, I get home and put into park. Hour later go out to start won’t start crank anything. I noticed the dash said it was still in reverse, but gear shifter is in park. Couldn’t change gears, key on off, brake pedal pushed no noise at the shifter, nothing. Reverse lights were on. Then, after just messing with the shifter holding the brake down, after about 20 mins it let me shift it to drive and then back to park. Once I got it back to park starts right up.
So now, I have to shift it into park firmly, and it takes 5-10 seconds before the dash lights up park. Delayed going from any gear into park, but park to any gear is normal. Any reason for this? Mechanical like the shift cable, or tune computer related? Oh and now when I hit the lock one time on keypad I get multiple beeps, that’s different. And while the car is waiting to go from reverse to park, the idle is staying around 2k rpms, then it finally reconginzes park and idle comes down.
I’m definitely a newbie when it comes to modified cars, I’ve always like fast cars but the ones I’ve owned always been stock.
Any and all input would be appreciated as I have no idea where to start other than things that I have googled. I’m pretty sure it has a small vacuum leak, the tuner pointed that out durning the tune, just a slight whistle sound at idle.
