A buddie of mine has a 94 Lt1 Camaro, with no exhaust and bout 120k on the clock. When ever he does a cold start the car runs fine but if he goes to the store and hops back in and starts her up after 30 minutes or so, the car dosnt wanna run properly. I dorve it yesterday and it like shutters real bad when you step on the throttle. I told him i think its a fuel delevry problem, but can you guys give him any other advise on what to do or what to look for.

 

well you answered your own question when you said, "camaro." haha. just kiddin'. I don't really know. but he should trade it in for a mustang.

Can you describe the shudder? Where do you think it's coming from?

 

uhhh, the entire car shudders. His way of fixing the probelm is to just "get her moving" like he cant stop holding the throttle or else it just dies. Oh and i thought u guys might like this but when he accelerates normally u cant even have a conversation with the person next to you. And when he floors it it hurts ur ears becasue its soo loud. But i do love seeing the blue flames shoot outa the headers and hear her back fire like crazy. Its great.

 

If the exhaust is completely off (no pipes or mufflers/cats), It may not be getting enough back pressure... Also, can you tell if the shuddering is from the engine or tranny???
