my car wont start after i turn it off in hot weather (like 90 degrees). i drive around for about 45 mins and turn it off. 15 mins later, i try starting it and it just dies. it goes to 1500 rpm and back down to zero and dies. i try another time and it goes to 1500 rpm then it bounces between zero and 250 rpm. car shakes and dies. then i wait like 30 mins and it start just prefectly.
can it be the relay?
what can be the problem(s)?
91 integ with 145000 miles

 

ONe thing is tat the car is a 91, and is pretty old, did u tune the car yet or andthing like tat? could be the cams r set wrong or just worn down from long life, check yur sprake plugs and think about investin in a new ride, the 91 teg is ready to say bye.

when my 88 civic did this, it was the main relay, so that would be my guess.
