My 87 560 sec gas has 300,000 miles and is running ruff, I have replaced cap, rotor, wires and plugs. Just wondering should I spend another 400 dollars + on new injectors or consider complete engine overhaul.
Does anyone have a ballpark idea of what that would cost ?
Thanks

Why not do a few preliminary engine condition assessments, such as a compression test and cylinder leakdown test before you spend an amount equal to the current worth of your car on an engine rebuild?
