i have a 91 accord ex auto its completly stock everything. every time when summer comes around the engine wont turn over and green light S flashes. so basically i have to wait there and keep turning the key twice to check if its not flashing and it will turn on as soon as it goes away. the car has 307 000 kms on it and weve had it since it was brand new in 91. what could the problem be here?

TCM might be taking a ****, check with some of the other 90-93 guys and auto guys.

 

check the codes you will find that it has a baro sensor code . the baro sensor is part of the tcm. so you might want to start looking for a used one the new ones are around 800 bucks....

 

sorry what exactly is a tcm?
