Tach quit working
Probebly a little history. My check engine light came on awhile back. I did the ignition on/off to get code.. it said EGR ok I out new on.. it went off awhile then has came back on. I changed spark plugs and now my tach quit working. I put new wires on. that didnt help. I have the 2.3 dual ignition so 8 wires and plugs and 2 coils. when its real cold out it barly fies and the tach starts to work but runs really really rough. then idle smooths out and tach goes to zero then wont come back up. Do you think I lost a coil? Or should I look for something else.
Please help. Motor runs smooth but seems to have a loss of power.
