replaced the spark plugs an now it's starts an runs but it
back fires an sometimes it will just go for a Lil bit an then
I'll be driving an just to get it up to 35 MPH I have to floor it

How did the old spark plugs "LOOK" oily? dry, tan, etc. check your new plug wires . Engine Left to Right is numbered 1-2-3-4 cylinder numbers, NEXT firing order is 1-3-4-2 look down at the distributor it rotates counter clockwise. An Image is better here it is. Regards

One looked like it had a oily black residue, the rest where blackish grayish dirty spark plugs, also have not replaced the wires yet an they are in the right order
