Post by Watchmasters »

I have a 1995 pontiac bonn. the other day it barely started. When it did it shook. I smelled gas also. when i barley press the accelarator down it really shakes rough. when I het the gas it is very sluggish. No back firing no engine light nothing.. when I am at cruising speed seems to be ok but once again no power.. also at drive in when idleing really bad gas smell....could i be a bad coil, egr valve, oxygen sensor? I dont know

Thank YOu

Yes, ignition (plugs / coils / wires) are the first thing to check.

Unplug the MAF sensor and see if the condition changes.

Pull the vacuum hose off the fuel regulator and check if you smell gas.
The diaphragm probably went out. And the rail pressure is wrong.
Gas smell is the tip off.
