I having a prolbem starting my 1990 integra...

somtimes it starts...sometimes it doesnt start

when it doesnt start..the ignitgion turns over...and even when I try jump starting it...it doesnt start...so its probally not the battery or the ignition

the previous owner said thst there is a realy igition prolbem...in warmer weather....

looked on the website...and called up autozone, pepboys, napa..they do not have it in stock...my local acur dealership said $59...can I get a better price somewhere else if this is the prolbem...
