Hey guys I have 94 pickup, when I get going up to speed in say, 3rd, 4th and 5th, as soon as I give it any real amount of gas, I'll have a misfire. That leads me to believe its fuel related. I have newer plugs/wires/cap in the truck and it seems to idle fine.

My buddy thinks its a fuel filter, and I'm wondering if that could be it? Or does anyone have any other ideas at what it could be?

Thanks for any help/advice.

 

Also, apologies for the terrible grammar. Damn phone makes it tough.

 

Check timing, did you replace the rotor or just the cap? Is the check engine light coming on? Might help to narrow it down to a certain cylinder or pair of cylinders if it has code.

 

The truck has been running fine for a year or so after I did the tune up. But it was just the cap, if I recall correctly. No check engine light either.

 

Im having the same problem. I let off the gas then then give it gas again and it cuts out and sputters and then goes away. I was thinking it was because i have a bad exhaust leak at the front flange and maybe theres air getting in and making the O2 not read correctly.

 

Good idea actually, I do have an exhaust leak that needs to get taken care of regardlessly, maybe that's it.

 

How bad is it. And where is the leak at. Mines at the flange and its pretty bad.

 

Not super bad, at least I don't think. The leak is up front somewhere, haven't pin pointed it yet. I have an appointment with the exhaust shop on monday.

I forgot to menton that I also have a leaky gas tank, is there any chance I could be loosing fuel pressure and that's causing the issue? The tank leaked for quite a while before this happened, that's why I never even thought of it. Regardless I have a new take to swap in, just waiting for it to be warmer than -4 outside.

Also, my buddy thinks it might be out of time. He's got the gun and we're going to try that too.
