OK so I recently did injector o-rings to find that I have mismatched injectors.
I have recepts form PO and it says 4 injectors were replaced back in 2012 from a local shop.
PROBLEM is I have early99. I have 4 AB injectors on drivers side (stock I assume) and 4 AD injectors on passenger side (3 stock looking ones and 1 yellow top Alliant power rebult?).
Is this bad? I was thinking of telling the shop that did it but I might be 2 years to late. The truck is not the easiest to start, runs alright (only one I have ever had so nothing to compare to)
All I know or have been able to find online is that they flow different amounts of fuel. Cant be good right??
