Settle down.. dont throw a rod.. hahaha lil joke.

A miss can be described as many things. Does it only happen at idle? Did your battery die? If so it may take your computer a little time to figure things out. Could be rich. Do you smell gas from exhaust? Any black smoke when you rev or idle?

Usually a minor issue will be masked with some throttle.. an idle is a tell tale of the condition of a motor.

This could be bad fuel.. did you treat the fuel?

Thanks for responding, the battery never discharge all winter I started it every 3 to 4 weeks and I treated the gas with Lucas and stabilizer. I also filled it up with 91 octane before putting it up.

If it continues, I have a scanner that we could try reading what is going on. If you drive over to St Rt 21 and go north, I live just on the other side of I-76.

With that said, if you didn't fill the tank all the way to the top, and depending on the day you last put gas in, you could have some condensation in the tank. Run some fuel injector cleaner and some water remover and see if the issue goes away.

We have had some pretty rapid warmups lately, with a lot of rain. Our cars are experiencing condensation. I had to put a dehumidifier out in the garage today. You simply could have some moisture in the electrical connections etc making it run rough.

Not running rich and no smoke just rough idle and a miss on acceleration

Do you have a timing light to see of all plug wires are firing ? But as I said, we have had such a rapid warm up with rain, the condensation built up all over our cars. I took a gallon or so of water out of the air in the garage in just a few hours.

After everything dries out, it might go away. If it doesn't then I would start to do some checking.

Thank you for your responses, drcook I live right off rt 30 so I'll be in touch if the fuel conditioner doesn't work

Put 50 miles on her and vary the RPM (that's polite for "Punch It!") and report back.

I'll bet you are good. Our cars like to run--- often.

If you knew where to look, you could see my barn as you drive up 21.

That is why I said about drying it out. My car actually had water drops everywhere due to the temp coming up so fast outside and still being cold inside causing condensation.

Looks like I'll need to wait a few days since it's going to rain for a while.I thought is could be a moisture issue, but just wanted other opinions .thanks I'll let you know the out come

do you have a fuel pressure gauge you can screw on your shrader valve? Its on your fuel rail. That would be a start
How old are your injectors?
Todays gas is crappy...had 2 yr old gas that would not ignite period
