Question about Pontiac Aztek

1 Answer

Misfires when put in drive

I have a Pontiac aztek. When I put it in gear it makes a misfiring sound that sounds like jiffy pop popcorn and has no power. When I put it back into park it smooths out and idles normal. Prior to this there were times when I was driving down the highway at 65-70 it would kick out of overdrive down into the next lowest gear. I would slow down to 40ish and it would run fine again for a few miles. I have basically rebuilt the whole top end of the motor. Head gaskets, valves, timing belt, all the sensors. **** thing has me stumped. Any Ideas?

Has any of the work been done by a repair shop or
just by yourself?

If a shop has been involved, I assume you wouldn't be here

Need to check for codes & work on & repair problems as you
find them

Going to need professional test equipment & use expertise, to
figure out whatever is going on there

faulty computer
faulty wiring
excessive carbon in combustion chamber, when hot, pre-ignition occurs. try using high octane gasoline first, but wait until empty, before filling up. it will take some time before the new gaz gets to the engine as the gaz lines and pump still have the old gaz.

another possibillity is water in the gaz tank.
when cold the gaz enrichment might compensate .

SOURCE: I have a 2004 Dodge

This presents a very unique and interesting problem.......the work originally performed on the vehicle is suspect, as the first instance of the vehcile slowing down, is very very very similar to a catastrophic engine drama, like a timing belt breaking, or if it did "skip" a tooth, WHY.......a timing belt does not skip a tooth unless it was not properly tensioned in the first place, or there is a problem with the camshaft or cranshaft gears themselves which would cause this.......so I am extremely cautious on their diagnosis of nothing being wrong......

As well as this

The 2.0 Liter SOHC and DOHC engines used in the Neon are interference engines. if the timing belt broke while driving there is about a 6 in 10 chance a valve came in contact with the piston. The only way to know for sure is to replace the belt and perform a compression check to see if any valves are not sealing, so I would ask them whether this was performed or not.

SOURCE: p38 misfires and pops when hot

it is possible that you have access carbon buildup around your valves or on top of the Pistons that gets hot and on cruise causes the engine to misfire.It is also possible that you have some water in the mix that is forced through under normal conditions that under cruise conditions is causing problems also.

Misfire on Cylinder 3 swapped plugs between 3 and 4 on Pontiak Aztek 2003. Misfire remained on cylinder 3. Swapped ignition coil 3 and 6 with ignition coil 1 and 4 misfire still on cylinder 3


Spark Plug swapping is a waste of time

You may never have a failed plug in 70 years
of driving

Now you move on to professional help

You could have failed valves,failed intake gasket
or other issues

Try a new plug wire on cyl 3 if that doesn't fix it you could have a bad valve or compression problem on cyl 3 Try doing a compression test also If it has injectors for each cylinder you could have a bad injector for cylinder number 3
