where does it max out at??
 

where should my 88 fc with no mods rpm out in first gear??? im really not sure mine reaches around 4000, and shouldnt it reach up around the red line before its needing to shift? thanks

Of course you should be able to reach redline (7k RPM) regardless of what gear you're in. Is this with an automatic or manual transmission?

its a manual transmission and mine will only get about 4 to 4 and a half before its needing to shift i dont know if my tac ometer is miss reading or whats going on??? i know i have been having problems with my gauges and all

what MPH are you at when it hits the limiter?

my speedometer cable is broken right now its kinda hard to get a exact reading on how fast i am going by the time i need to shift from first gear

i'm pretty sure its just reading at 4 but actually the rpm might be around 7-8 since your guages don't work... i installed a tachometer once on a car and it would red line at 3.5 when the stock tachometer would be reading at 6-7 if that makes since to you

yeah but why would you install a tach if the stock one still was working??? i understand what you are saying though, i just wanna know for sure what the problem is if possible, thanks every one

Replace your speedometer cable. Will the tach reach redline if you're just free-revving the engine out of gear? If it ends up your tach is just reading wrong, you could be doing serious damage to the engine by over-revving it.

ill be replacing the speedometer cable asap, and yes the tach will reach redline when im just free revving out of gear , and i am very careful about over reving while driving i dont rap it out because of the tach ometer problem i just play it by ear

hey so i got my speedometer fixed, i put a new cable, and yeah it works well but while installing it i dont know if i loosened something but now my tack dont work at all what should i do or how should i go about fixing it, i got down to my cluster and could not get the cluster out it felt as if it was being held, and i did not want to rip it out what should i do??? thanks

There are 2 plugs on the back of the cluster that are very hard to pull off. Each one has a couple tabs that you press in, then work it side to side a little as you pull. Other than that, only the speedo cable will keep the cluster from coming out. If the tach stopped working, you probably loosened one of the plugs without realizing it. Take the both plugs off and make sure the connectors inside are where they're supposed to be, then reinstall.

k how do you press in tabs on the back of the plugs if they are very hard to get to??? thanks

hey i got the plugs un pluged, and re-pluged everything back in, and still no tac i dont really know where to go from here any info would be really appreciated thanks

dunno if this will help my tach didnt work the first time i got my fc i changed the coils and then it worked..... well

i have been reading about like grounding the coils cause that might make the tac work or somthing like that, what did it cost you for new coils???

and if anyone knows how do i check the ground and possibly re-ground it in a better way or something??? thanks

help with my tac and coils
 

i have a 88 fc NA, and recently my tac quit working, i have been reading around and have been gettin that my coils could have something to do with this? either bad grounding or maybe there going out, and hopefully the tac in the cluster is not ruined any help would be much appreciated thanks! :(
