First, check your air filter and O2 sensor. Both probably need to be replaced. If the HC is up, change the plugs and wires too. If the vehicle is carburated you probably don't have an O2 sensor.
what does it mean when my IGM is low at 28L
Let the length of the shorter leg be L, then the longer leg is L + 14.By Pythagoras then 262 = L2 + (L + 14)2 = L2 + L2 + 28L + 196 = 2L2 + 28L + 196676 = 2L2 + 28L + 196 : 2L2 + 28L - 480 = 0 : L2 + 14L - 240 = 0This can be factored : L2 + 14L - 240 = (L + 24)(L - 10) = 0As only a positive number answer applies and this is when L - 10 = 0 : L = 10.The length of the shorter leg is 10 feet.
under exaust manifold on passenger side
The firing order is: 1-2-3-4-5-6
Should be around 40 psi
