speedo maxes at 30 and constant beeping under motion.
Ok im sorry im trying to get ideas on where to diagnose or fix this issue. But i havent had a lot of time to work on it cause when it rains it pours. Tiny backstory been on here before but got busy so havent been in forever. Ok i got a fiancee and got a house and a baby all in the same time frame. Also been working on a top end rebuild in an 94 isuzu trooper. Well my dd which is an 05 gmc sierra duramax computer decided to act up so bad my scan tool and tuner will not even talk to it among other issues so i go to my backup which is my 74 buick electra 455 which i love but needs work. So i have a brake leak which im pretty sure is in the master cylinder i have to pump the brakes to stop whereas before i got it to feel like it could stand on its nose if you tapped the breaks. So under movement and 99% of the time it lets out a loud audible continuous beep and i also found out my speedo only goes to 30 and then pegs out. Now be gentle cause like i said i have barely had time to even glance at it really. Just looking for a direction to take or hell a cure. I have a laundry list of upgrades planned for it including eliminator intake over stock and headers over manifolds and so on. Now that i know no MATTER what i do it will NEVER be considered a true classic or probably even worth entering local car show. So that has cut my leash on it to do what i want and i have always been a fan of power and neck snapping reaction time. Sorry it was so long.
