i have been having some probs with my my 1984 trans am, on top of a recent idle problem and really bad idle problem i have noticed to things with the crankshaft pulley and have no idea whats wrong or how fix it, i have also been having issues with the starter which has been having trouble turning over the engine i made two videos of each prob on YouTube here are the links

( pully issue )

( starter issue )

any tips or help is Greatly appreciated!

Thanks!

 

How long ago was your last tune up?

 

In a loud server farm atm so hard to hear vids.

Pulley - assume the problem is the wobble. Balancer looks ok so - pulley bolted on ok?

Starter - assume the prob is slow crank? Old batt, damaged cables, dirty or corroded connects or terminals.

 

i recently bought the car off a neighbor who got it from the original owner the last time it was serviced was probably a while ago under the original owner so i cant really say

 

thanks! maybe you can help me out with something else, the car also has an erratic idle (ex fire up in morning idle at 700rpm, fire up in evening and idle at 2000 rpm) also it seem at low idle that it shakes the car violently, any ideas?

 

Pretty generalized symptoms there - could be a bazillion things. This carb, crossfire, tbi, tpi, what?

Some general solutions - like Edwardgp said, tuneup stuff - plugs, wire, rotor, filters, fluids etc. Look for vac leaks. If carb - dismantle, soak and re-kit. Or fast-idle mechanism. If fi - hows the fuel pressure?

 

well i went ahead a bought new spark plug wires and the cars idle is alot more stable and and sounds like its running better but the problem i'm still faced with is the violent shakings low idle (1000rpm), even when i rev the car higher it still shakes.
has this ever happened to anyone? any ideas?

 

could it be the carb or is it something else making the car shake?

 

IMO I would give the rotor and distributor cap a good look.

 

do you think the cap and rotor have gone bad or is the timing off?

 

Outer lip of the pulley is slightly bent, not cause for too much concern, mine was too. Slow start could be a weak battery. Replace it.

For your idle issues, is this your first carburetted car? They act a little different and fast and slow idle depends on what you do to the gas pedal before starting it.

In short there is a specific procedure for setting the choke and fast idle. Once the car is warmed up, a slight kick on the gas will knock the fast idle cam off and the idle will drop down to 700 or so. In the mean time it's going to shake and run rough.

If you are unfamiliar to this, as I was, it can seem like the idle has a mind of its own.

 

i helped him today with the car and the battery is weak i had my 200 amp max charger hooked up to it to start it since the alternator belt broke and it didn't have a problem cranking with it. it didn't get gas for a while until gas was poured directly into the carb then the rest of the time it didn't have a problem starting it kept idling when not in gear at 2200 rpm. then it finally went to idling at 1000 after a little adjustment it still is having problems though. it also looked like it had weak spark. the spark was yellow instead of the regular blue color

 

went outside in the rain and decided to go the the convince store at the corner. when i went to turn it over all the electronics on it died. but after slightly tightening the Negative and positive terminals, everything came back on, and get this, the starter is turning over with twice the power it had in the video and starts fast strange but im glad it was an easy fix
