There is no lights on, but funny you ask, i just talked to guy that gave it to me. He said it got a new timing belt/chain and this is when an acceleration issued started for him, but for him it was around and after 4000 rpm, since i have been driving it it is before 4000 rpm sometimes and never after, when it gets around 4000 it takes off like it were a vtec but its not its a d15, so maybe the timing should be adjusted, last time i used a timing light was on my 91 acura ls and i dont really remember how i did it to fix it that was 10 years ago and a first and last
