I have a 2004 Saturn Vue 3.5 AWD V6,compression is good on all 6 cylinders ,I had a little oil on 2 spark plugs in the back head cleaned them and it is running good but I have a lot of white smoke coming out of the exhaust and the temp lite is coming on but the gauge is staying under half ?

P0302, see I now it, but is it only 1? DTC error?
2 engines , or where? and up to 5 world wide, NO VIN
Engines, Mitsu. no clue told.


V6 2.7L? (so says dodge.com USA> go this?
2.4 L EDZ I4 4G64 I4 DOHC and SOHC
2.4 L EDV/EDT turbo I4 (Mexico)
2.7 L EER V6 ) i GUESS THIS IF Usa CAR. has 6 COPS
Coup?:
2.4 L 4G64 I4
3.0 L 6G72 V6


my best guess USA is VIN K engine, no vin told so engine is UNKNOWN,

it means, this, only.
Low combustion on #2 cylinder, (spark,fuel injection or compression bad)#2
#1 is on crank pulley end. #4 is at transmission I4, F1234R
rear means tranny end. oK?
v6
all V engines 99% #1 is the bank V that is most forward cyl. of all.
to the crank pulley's
2nd is always 2nd in firing order, always,and PCM dictates it.

2.7l v6 24v ffv . dohc mpi engine.
firing order, 2.7L 1-2-3-4-5-6 even odd ;odd banks.




causes (v6 cops)
1: spark plug bad #2
2: spark coil bad, COP 2 dead? or weak or boot bad.
3: oil flooded inside the spark plug well, shorting all above out.
4: injector bad #2 (omg PCM, nah) swap 2 top find it;
5: compression fails #2
only 1 code told so answer is 100% based on 1 code only 302
6: rare bad cam lobe.
7: rare cracks in head , antifreeze leaks to #2 combustion chamber.
8: oil leaks to #2 via all classic ways.







3.0L v6


2.7L


2.7L V6 order
1-2-3-4-5-6

Questions;

Mileage?
Fuel trims?
Mysteriously losing coolant?

Suggest you do a compression test of all 6 cylinders for a comparison. Keep track of the spark plugs for clues... sooty vs clean, odd bank vs even bank.

the misfire fault (p0300 for random misfires or p 0301-08 for individual cylinder misfires) is seldom as a result of plugs
It is more likely from
low fuel pressure ,pump , EVAP not venting ,dirty injectors , wiring to the injectors , injector control, or ECM
simple fix is to put a can or 2 of injector cleaner in the tank and go for a good drive
next is to replace the fuel filter
more involved is to have the fuel pressure tested to check for pump and pressure regulator operation

Head gasket blown, water in the oil is a good indication, pull the spark plugs and see if there is coolant in the cylinder, do a compression check.

Hey Guru???
What'd you do rank yourself a guru? Cause you sure don't KNOW what you're talking about.
Honda V6 3.5 engine is in the 2004-2007 Saturn Vues with 6 cylinder engines. It is the ONLY V6 offered. The old version was from Opel.
The trans dip stick is on the right side of the engine while the oil stick is front left.

It has a maintenance recomendation from the manufacturer for replacement of the spark-plugs at 100,000 miles. You don't list mileage or V6 or L4 cylinder. Make sure engine is cold because the cylinder heads are aluminum and can be damaged if plugs are removed hot or overtightened upon reassembly. Remove spark-plug wires and replace spark-plugs. Sometimes the wires break when you remove them and will require replacement. If you coat the inside of the wires where they connect with the plugs with dielectric grease it will help prevent the wires from breaking upon future disassembly.

When and how to change spark plugs for 2002 saturn vue v6?

How do i check the transmission fluid in 04 awd v6 auto

they are full of it, u should show oil pressure as soon as the engine starts, this may be a sticky guage or a sender but that advice they gave u is bull, that is for sure, I am a GM technician.
