Hey guys first off I'm new here so let me start by saying HI and thank you to anyone who can help me solve my long problem. Here it goes

I stopped and filled the 93 Cutlass cierra up with a full tank of the usual unleaded. What was unusual is when I started it up to leave it bogged down and wanted to die like I had water in the the system so I grabbed some additive to dry up the water through the lines and whatnot. Well I am driving along and all is wee until it starts bogging down likes its misfiring on a cylinder does that for a couple minutes then catches right back up to speed, the tranny is fine. So I think nothing of it then the next day it does it again and its getting worse, I went and put new spark plug and wires on it and now its just actin completely like junk its not even idleing smoothly and all the wires are run to the right cylinder. A local mechanic said it sounds like a fuel injector is bad and maybe a coil but then coils were replaced. I don't know what to do any help is appreciated as this is my only car and it has 173,000 miles on it if that helps Thanks Tyler

 

anybody

 

If you tunedit up and it's running worse now, I'd look at what you replaced. Maybe you cracked a plug, have one gapped way wrong, knocked a vacuum line off somewhere.

 

fix cutlass easy to work with and cheaper in parts in long run
83 better metal to check its weight.

 

Ok guys I've noticed this problem only happens at normal operating temperatures, it does not do it when the car is first started or when the car is still warming up, and it seems to do it a lot more frequently when I am in drive

 

Anyone think of a fuel pump ? 1 thing I seemed to replace on every cierra and cavalier I worked on.

 

I was thinking of that or someone said maybe the fuel filter is clogged I'll be pulling some more things apart I guess

 

Well its not my fuel pump that is working good replaced the fuel filter thats nolt it. I'm thinking maybe I have a clogged catalytic converter or maybe is it the transmission?
