First, is this a brand new balancer or jkyard? did you matched both balancers, if not wrong you have a 3.8 lts coil packs? need litlle more info, setting the crank sensor right is a little tricky you could damaged it including your new balancer

Not enough info but with that many miles you could be looking at burned valves ang clogged cat converters.

My 2008 Ford Bantam seems to have strange firing order 1-2-4-3? is this correct. Also the distributor does not have an H.T. lead. Can someone help please?


4 cylinder engines can have both firing orders
the more common one is 1-3-4-2 but some manufacturers have the other firing order
it depends on the manufacture of the position of the crank pin
some reason for it are
less harmonic vibrations
less stress on crank webs
easier manufacturer
for the missing problem run the fault codes and check for ambient temp sensor , maf/vaf sensor or BARO sensor problem

91 chevy cav z24 5 spd will not start @ times sounds like no fire other times sounds like no fuel.Replaced fuel pump,timing chain, crankshaft sensor,oil sensor,map sensor,body throttle accel sensor.st


Pull the air cleaner off and crank the engine. If puffs of air come come out of the throttle body when cranking the engine then the timing is not set correctly. Otherwise, after cranking pull a spark plug and see if it is wet with fuel and if so this indicates an ignition problem (coil, distributor/cap/rotor or faulty ECU).

Motor is miss firing p3o3 changer ecu after few mins mis fires is my crank position sensor not reading the third cylinder for some reason i did a motor swap ran new motor 3 or 4 hours had miss shift...


your crank position sensor does not read individual cylinders, only the position of the crank shaft. make sure the plugs and wires are good, check the spark coming from the coil, make sure there are no vacuum leaks at intake manifold, check timing, then do a leak down test to make sure you don't have a bent or damaged valve in the cylinder head.

Car running on 3 cylinders, changed spark plugs but still running rough


Do a compression check. You want to check and see if you have good compression across all cylinders or if you've blown you head gasket or rings. If you don't have any check engine light indicating a faulty crank position sensor, or a misfire on a cylinder, you may have fire on the cylinder but if there is no compression or low compression the vehicle will run roughly. If you need directions for doing the compression check or manually checking the Crank position sensor and other sensors that could cause this condition I recommend the Haynes Repair manual on your vehicle. Most major Auto Parts stores carry both Haynes and Chilton's manuals on vehicle. I prefer Haynes but Chilton's will do as well.

Misfire in two cylinders


Check to see if the two cylinders misfiring are on the same coil pack. If so, change the coil pack in question.

This happened to me on 1997 Cadillac Deville Limousine.

Also, check for a blown head gasket with compression test.

I'm getting code 0016 and 0301 on my 2005 gmc sierra pickup, vortec 4.3 v6. Won't start.I've had those codes for several months, but was too busy to get it fixed, with occasional rough starting or poor...


P0016 Crankshaft Position - Camshaft Position Correlation
Replace the Crankshaft position sensor, it's located on the passenger side by the harmonic balance in the front of the engine. Inspect the wire harness and make sure you also buy a can of brake cleaner to clean all the dirt from that area since the sensor is magnetic and will pick up any metallic dirt and will cause faulty reading to your ECM.

P0301 is an indication to a missfire to cylinder #1 which is most likly related to the crankshaft sensor being bad.

Replace the Crank sensor first and it take about 20 min from start to finish. Good luck and keep me posted.
