Got the cooling issues sorted out- thanks guys. Now on to a little more serious (?) issue.. heh..

The car is running rough - the tach is jumpy, im cruising around the block under 1500, the tack jumps back and forth 0-1500, and when you gas it. its not a linear sweep, its back and forth - i replaced the TFI module - same issue. Ideas?

383, MSD 6a+boost retard, 42# injectors, old hypertech chip called for 30#'ers.. (getting fixed soon.. chip should be here tuesday..). It was running great the other day tho - ideas?!

Anyone that can figure this out and have it work. i will send you beer money!

 

I had a problem exactly like this. After the car became warm the tach would jump around. The car would jerk as if the ignition would quickly shut off, and then come back on. Took me forever to find the problem. It was a loose ground wire on the back of my passenger side cylinder head. If I were you I would check the grounds on the heads.

 

Also might be a bad pickup coil. You would need to remove the distributer and take off the gear/shaft to remove it.

 

Holy ****! that sounds exactaly like it! runs good when cool, but when she warms up it gets jumpy! i will go check the grounds. thank you!

Joel - the distributor is brand new.

I found one - the copper peice going to the block was broken.. grr, its happy now - hopefully this is exactaly it!

 

So, how about that beer money?

 

hehe.. not so fast :P when it warms up, it still gets jumpy - any other ideas? think the MSD box took a ****? its got a 6A with a BTM box..

 

I would unhook the MSD unit and try running it the stock way. But I still think you have a loose wire somewhere, remember the ground wires have to be on their tight.

 

*rips hair out* yeah.. ill screw with it tomorrow or tonight when i get home from work - hey, do you ever cruise up to the car shows i.e. the cooper & warner one? i want to check out your car - im considering doing the T56 as well.. as the 700r4 is not going to hold up much longer.
