got an 88 crx dx...before it idled at 1250, with a ecu code throwin "coolant temp sesor" thats been replaced and now it idles around 750, but apparently it is bogging wen accelerating out of that rpm speed. my brother said it could be distributer cap, spark plugs, or rotor. anything else it could be?

 

If those are old: plugs, wires, distributor, then replace the stuff. From personal experience, when my engine bogged down like that, it was when my timing went off, and got advanced. Try fixing it, or retarding it.
