Ok well just got the car back from the shop due to a bent valve. Well got it back all seemed normal til last night and today. It happen after i made a left turn. The car started to bog down as if it was given tooo much gas or as if it didnt have enough gas. So during that time i would give it more throttle and it would get worse. Then all the sudden around 2.1-2.4k rpms it jumps and kicks in like nitrous, but really its going back to normal. Now i have a MSD blaster coil, MSD ignition box, Retard box, and a Digi wndow switch for my eletrics thats ignition stuff. I also have a walbro 255 pump that ive had for about 3 years.

I have msd 8.5mm wires, good spark plugs Tr6's. Mods are 355 big cam, stock heads, full bolts etc, along with 3200 stall..

Anyone know an idea what it could be?

I also checked everywhere for a vacuum leak maybe, but nothing.

 

I was having a bit of a similar problem. The folks in here pointed out to me that I might have been starving my torque convertor. So I checked the level, and sho nuff I was a little low. Added a quart and didn't have a problem again. Until.........

I was on the way out of town and was getting a bit low on fuel. I decided to fuel up in the next town. So as I'm getting on the interstate, I decided to goose it as I was getting on the on-ramp. It bogged terribly and I couldn't get it to work right for quite a while. So I backed up all the way down the ramp and filled my tank at the station there instead of waiting for my favorite fuel stop.

That seemed to cure the problem. So apparently my real problem was that as I was hitting the curve under acceleration, I was sloshing the fuel away from the pick-up and starving the engine.

So, how much fuel do you have in your tank?

 

my cars giving me hell to.. bringing it to the shop in an hr... your not alone!

haha
cory

 

enough!

 

well just drove it again and it did it for a good 3 gases. Seems like its dragging or something. Then it will hit all power at once.

On one of the tries it went all teh way up to 3k and wasnt even shifting yet. btw its a A4. So its got to be something.

Checked tranny fluid and it was all good.

 

You think the MSD blaster coil could be causing this?

 

is it throwing any codes?

 

i think i fixed the problem. The wire from the coil to optispark wasnt all the way on.
