Hey Guys, I have an 89 integra with dohc d16a1 and sometimes when i first start the car especially on a hot day my tachometer alog with some of the dash lights stops working. Such as my brake light when i put the brake up, and some of the check lights when i have the key on accessories. After driving a few miles the tach will start working again and the oil light will flash until i turn off the car and restart the engine. At which point all dash lights resume normal function. I was wondering where i could begin diagnosing the possible grounding/electrical issue and what your thoughts may be. Thanks!
