sorry internet conection was screwed up forgive me :hail: but i was tryin to say that my car was havin problems exelerating the problem is that the car exelerates really slow and wont swich gears right it will get to like 30000 rpms and wont go anymore and it wont exelerate any faster no mater how much gas im giving it it only does this some times like ill shut my car off for a few and it will go away for a while but not all the way, accompaning this problem is an oil leak, dont know if its related but thats whats happining... again sorry about the triple post thing it was a accident

 

STM,

What year/engine/fuel system do you have?

By your description, the problem could be caused by sevcral possibilities, including a clogged cat converter, otherwise restricted exhaust, poor fuel delivery, weak ignition, massive vacuum leak, etc.
A little more detail on the car may help.

 

its an 84 pontiac trans-am v-8 305 with flowmaster muffler but other then that its stock exaust and engine also already replaced sparkc plugs and spark plug wires just like a month ago (dont drive that offten)

 

STM,

Starting with the basics, we need fuel, ignition at the correct time, and compression to make the engine run. Presuming that there is no serious mechanical damage to the engine, we can put the compression question aside for now.

The oil leak is most likely not related, but should be addressed anyway. Clean the engine, monitor the surfaces to locate the source(s) of the leak(s), then repair it.

For the performance issue, start with the fuel delivery. If I am correct, you have an E4ME Rochester Quardajet carburetor. Replace the fuel filter if you haven't already done so. You might also clean, inspect, and lubricate the choke linkage. Make sure the choke opens fully when the engine has reached operqating temperature.

As for the ignition, the new plugs and wires are a good start. (Incidentally, what was the condition of the plugs when you removed them? They can be your best gauge of how the engine is running overall.) Don't stop there. You should also remove teh distributor cap and inspect it and the rotor for wear, damage, and pitting of the terminals.

Are there any other symptoms, like overheating, smoke, hard starting, or poor idle?

 

well i am experiancing a ruff idle and some over heating problems its not too bad but it is running noticibly hoter then it normally does and doesnt exelerate as good as it used to, and im getting really crappy gas milage oh and i think its my cat cuase im getting like only half as much exaust out the back as i used to, if that

 

I think you answered you're own question......

A clogged cat can cause overheating, rough running, WAY down on power , and you noticed less exhaust coming out??

Check the cat. Sometimes you can bang on it with something and hear the insides of the car rattling around inside. Be AWARE that if the cat has failed, and the crap inside has broken up, it will be in exhaust pipes as well sometimes. Make sure nobody's behind the car after replacing it......and rev it good



HTH

 

well i dont think i can change it for awhile unless i can find a super cheep one cuase im kinda runnin on empty cash wise, is there any way i could just clean out my cat or sumthing just for temporary until i can get some money together or any other option that im looking over maybe.....

 

Try smacking it with a hammer or mallet while its running, worth a try if have to get a new one anyway.

 

what would that do ?? might try that
