i just rebuilt my 91 Prelude. it has a B21A4 engine. There are a couple of problems i have..... first of all the check engine light comes on, but only after like five minutes of driving. i was wondering what are all the possible things that would make this light come on. also two days ago my engine purged all of the antifreeze off the back of the block, ive checked everything and i cant find the problem. and finally my ANTILOCK light is always on, now im not a brake person but i dont know what is wrong with the ABS, if anyone could help it would be most appreciated. thank you

 

Im not sure about the Check Engine Light, but the ABS light is a common problem among preludes. From what i have found out, most of the time the problem lies in one of the two rear wheel ABS sensors. Mine came on all the time after i got about a quarter mile down the road, so I just took out the light

 

Pull the CEL codes - that should give you a better idea of what the problem(s) are.

Yup; your engine throws codes FOR A REASON - CHECK THEM.

We can help you after you do that.

 

im gonna guess egr though, that how it acts, waiting to pop the cel.....

definitely check though....and as far as purging all its coolant....you either have a hole in a hose or possibly (i really really doubt it) a freeze plug leaking....

 

what do you mean by pulling the CEL codes
