alright my friend is having a problem with his crx (88 si) it seems there is alot of pressure being built up in the coolant system and alot of hoses are breaking...if anyone could shed some light on this it would be helpful...also we just replaced the thermostat almost 2 months ago and now it begins to be at a normal temp then all of the sudden shoot up then come right back down like its sticking bad but when we took it out to look at it today it opened fine...and he also has alot of hesitation, when u get on the gas it like bogs down like its about to stall and then it revs up like a bat outta hell...anyway to stop that? any help is appreciated, thanks in advance
