Guys i bought a 97 motor with a 180 pump and it has a bad shake at idle when i crack number 1 injector the shake goes away i swapped injectors to different holes and the miss is still at cyl 1 i swapped delivery valves and holders and it is still there i also pulled the injector and pressurized number 1 and have no leaking no smoke or blowby either any suggestion's
 
Ok I have it figured out.The person before me had put in 191 DV's. when they did they had gotten dirt between the valve and the barrel not letting it seat tight to the barrel.the weird thing is number 1 was clean but number 4 had rust and dirt between the barrel and valve. so i guess when i cracked #1 line it was balancing out with #4. hope this helps anyone else that changes there DV's make sure the barrel is clean .
 
Not to sound like a smartazz but no chit LOL

Glad you figured it out man. I had a dv washer in a pump once causing a weird miss. It was aliminum and the only barrel with one in it so I never saw it. Took a lot of curse words to find it.
