when i hit about 4k arms my tack jumps all over the place and it sounds like its backfiring and i have a huge amount of hesitation. also my car will idle around 500rpms when warm. any answers? please need help. thinking its the dizzy.

 

does it stop after it hesitates or keep going... check your main relay and dizzy

 

this happens to me as well. not all the time... but occasionally. I have an 88 CRX Si with a B18A1 swap. I'd check ur main relay and timing belt as well. my timing belt is going bad, i know that for a fact, and this could be the problem.

 

the hesitation does not stop, it continues until it hit redline, and will also on occasions hit redline earily. but it could just seem like that because the backfire are so bad and that the tach goes everywhere.

 

Are you getting a check engine light?
Any codes?

 

that happened to me and it turned out to be a bad timing belt tensioner.....it skipped a tooth and the valvetrain timing was all thrown off

 

yea my check engine like comes on when i am usually going on the highway, i have yet to check the code(s) its throwing. but it was on a few months ago before this problem started but the code's would not come up. i checked my dizzy awhile back and the shaft kinda looked loose, so i am kinda going more torwards a distributor problem. i got another problems on my hands now, i power washed my motor today after i used degreaser and i think i might have fried my alternator. this week has not been a good one.!

im attempting to fix a friends car.. she says that it hesitates once in a while and i drove it today and noticed it doing it while accelerating..

would checking the timing w/ a timing gun determine if it skipped a tooth?? or would i have to pull the valve cover off and check for everything to be at TDC?? im thinking this might be her problem.. but the valves sound fine and it does not do it all the time.. thanks
