NO BUMPING -CRX TOAD-

 

are u sure your car's timing is correct ?

 

no but would that cuz it

 

its probably not the cluster, how are you sure that its not actually idling at that rpm

 

because i know wat 1500 rpms sounds like and it definitly is not at that its at the stock 750 or so

 

my tach does the same thing. it says im idling at 1k but its so quite... but when i start to go the rpms sound like they are about right on with the tach

 

why not just install an aftermarket tach?

 

cuz i dont want a five inch spotlight sitting on my dash advertising for the rice buffet sorry i just hate how that looks and would like to keep it extremely stock

 

did you check your dizzy is it on time with the pulley just do a timing test.

just try it
