Im just wondering, what are some signs of lack of compression? My car runs sluggish when i try to full throttle on it, it wont even speed up, it just starts to suck. The car will go fine if i slowly put my foot on the gas pedal, but its annoying as hell doing that. Just wondering if my problem might be compression issues?

305 TBI , 5 speed.

 

have you checked your fuel filter?My 305 H.O was doing similar when i first bought it.

If your worried about the compression,just pop a few plugs out and run a compression test on it.

 

Signs of low compression: a dead miss, a very rough idle, burning oil (due to worn rings,) no power, etc.

Check the simple stuff first.....since it does fine if you ease into it a clogged fuel filter seems likely. A weak ignition system will also cause that type of problem, as will a clogged air filter.

 

Sounds good, I'll pick up a fuel and air filter for it tomorrow and see if it helps.

 

Hopefully that solves your issues.How many KM's are on the engine anyway?

 

There's 190,000 km's on the body... the car was kept in great condition, and i was told it still has the original engine, it hasn't been rebuilt or anything...

But this summer I plan on either rebuilding my 305 TBI and adding all the chrome accents while putting it back together... or if I feel like I can afford the gas, I might get a rebuilt carbed 350 with some basic performance upgrades.

I CAN'T WAIT UNTIL SUMMER

 

Your problem sounds like low fuel pressure. I had the same issue a month or so ago. The faster throttle change I gave it, the crappier it ran. If I floored it, the car would get zero power and would usually backfire. If I increased throttle smoothly, it would run almost normal. I changed the fuel filter which helped some, but the problem didn't go away until I got a new fuel pump. If I were you, I'd do a tune up including cap rotor o2 sensor and fuel filter, then if your problem isn't solved I would get a fuel pressure tester before I changed the pump. The pump is a pain in the *** because of everything thats in the way of the tank.
