Hey guys I am having a problem with hesitation. It seems fine at start up and when I start driving for aprox 5 min or so I'll punch it and it has no guts. In ur oppinion what could it be? it shouldn't need tune a all it has is a 3" exhaust with the stock exhaust manifolds. I will say though the exhaust has a leak with probably a lot of the problem. I was just wondering what else it could be because I think the leak is by the muffler but not sure if there is another leak elsewhere.

Is this question in the wrong spot? The car is TBI and I was kinda wondering if it might have a little bit to do with the TBI. I mean I know that it could be any thing like I was also thinking ignition coil or the module because I did a tune up and those were the only things I didn't look at or change while I was doin the tune up.

These cars pull a little less strong before the engine reaches operational temperature, but its probably not your problem.

I would check, timing, Fuel Pressure, then 02sensor (if no exhaust leaks near it). Vinaldl datalog would help make diagnosing easyer.

ok thank you, yea thats one thing that I'm not sure about my dad and I put a new timing chain cover on it because the chain was rubbing on the oem cover and rubbed a hole through and I'm not sure what we set the timing at I think we set it at 0 not sure though.
