Variable valve timing

no year told nor any engine told or a VIN
why not tell the job first???
or read the service manual , buy it.
is the cam timing lost , say CAM
my wild wild guess, is cam belt snapped/
keep in mind if the engine (a secret) is the interference type.
the next step you do may wreck valves in the DOHC head.
do not crank it over now or $2000 damage
post your vin first
then tell what failed. name 1 part out of time./

That is a tricky question! Some engines use BOTH ENDS of camshafts for certain things! Are the lifters above the valves? If so, and you pick up the cam(s), the valve lifters could (1) fall out, or (2) fall apart! You DON'T want to mix parts up like that! But what you CAN do, is loosen the cams, then put a piece of black plastic electrical tape around each valve lifter, so they cannot fall out, nor fall apart when you lift a cam out!

The Mazda dealer should be able to help you.

If noone has the info I would go to mitchell1diy online and for ten bucks pay for all the procedures. It may have what your looking for.
Please do not rate me unless its good since I really don't have a perfect answer for you.

How to read a VIN
1st character- Identifies the country in which the vehicle was manufactured.
For example: U.S.A.(1or 4), Canada(2), Mexico(3), Japan(J), Korea(K), England(S), Germany(W), Italy(Z)
2nd character- Identifies the manufacturer. For example; Audi(A),
BMW(B), Buick(4), Cadillac(6), Chevrolet(1), Chrysler(C), Dodge(B),
Ford(F), GM Canada(7), General Motors(G), Honda(H), Jaquar(A), Lincoln(L), Mercedes Benz(D), Mercury(M), Nissan(N), Oldsmobile(3), Pontiac(2or5), Plymouth(P), Saturn(8), Toyota(T), VW(V), Volvo(V).
3rd character- Identifies vehicle type or manufacturing division.
4th to 8th characters- VDS - Vehicle Descriptor Section. These 5 characters occupy positions 4 through 8 of the VIN and may be used by the manufacturer to identify attributes of the vehicle. Identifies vehicle features such as body style, engine type, model, series, etc.
9th Character - The check digit "character or digit 9" in the sequence of a vehicle identification number (VIN) built beginning with model year 1981 (when the 17 character digit format was established) can best be described as identifying the VIN accuracy.
A check digit shall be part of each vin (since 1981) and shall appear in position
nine (9) of the VIN on the vehicle and on any transfer documents containing
the vin prepared by the manufacturer to be given to the first owner for purposes
other than resale. Thus, the VINs of any two vehicles manufactured within a 30
year period shall not be identical. The check digit means a single number or letter
"x" used to verify the accuracy of the transcription of the vehicle identification
number.
After all other characters in the VIN have been determined by the manufacturer
the check digit is calculated by carrying out a mathematical computation
specified. This is based on vin position, sample vin, assigned value code,
weight factor and multiply assigned value times weight factors. The values are added and the total is divided by 11. The remainder is the check digit number.
The correct numeric remainder - zero through nine (0-9) will appear.
However, if the remainder is 10 the letter "X" is used to designate the check
digit value/number.
10th character- Identifies the model year. For example: 1988(J), 1989(K), 1990(L), 1991(M), 1992(N), 1993(P), 1994(R), 1995(S), 1996(T),
1997(V), 1998(W), 1999(X), 2000(Y)------2001(1), 2002(2), 2003(3)
11th character- Identifies the assembly plant for the vehicle.
12th to 17th characters- VIS - Vehicle Identifier Section. The last 8 characters of the VIN are used for the identification a of specific vehicle. The last four characters shall always be numeric. Identifies the sequence of the vehicle for production as it rolled off the manufacturers assembly line.

Vehicle Identification Numbers (VINs) are used to uniquely identify motor vehicles. Prior to 1980 there was not an accepted standard for these numbers, so different manufacturers used different formats. Modern day VINs consist of 17 characters that do not include the letters I, O or Q.

what is the voltage of the battery when running, voltage when turned off, voltage after headlights are on for 10 minutes. is the battery good? how do you know. these take a sealed gell cell battery.

It should only need little plastic pins and screws. You could get these at Auto Zone or another auto part store near you.

clean the egr valve out with carb cleaner will work for a while but cant promise how long

check globe ,wiggle wires,check fuse clean light housing
