CHEVROLET TRAILBLAZER COMPRESSION PROBLEM

2006 Chevrolet Trailblazer • 120,000 miles

Has a mis at idle or load. First it was giving po301 then I replaced the plugs. Now getting po306. Also had an po106 but replaced map sensor and that went away.

Did you gap the plugs?

Was told by store iridium plugs were factory gapped

Could be a coil failure as well. Have them checked.

Bought 1 new coil and tried it on all cylinders but responded the same on all 6.

Check no.6 cylinder compression, injector and no.6 wire resistances
