SOURCE: recommended oil for a 1988 mazda rx7

are you sure you want to start using it. Yes it is a great product but it wont bring an old engine, magically, back to life. If anything it is thin like moble-1. So on an old engine it could start to leak oil from the main seals and/or start to smoke from worn rings. and royal purple is a full synthetic. Don't mix it with conventional oil.

SOURCE: hi .....my mazda 3 2008 gas pedal not responding

I don't know if your Mazda is all electrically ran, but it sounds like it. It may be as simple as a fuse, but mine ended up being the entire fuse block had to be replaced. Also there may just be a loose connection, especially after an accident.

SOURCE: clutch Problems with my rx7

More than Likely your clutch reservoir is low on fluid and has leaked all the fluid out so check that first if the reservoir is empty then fill it with brake fluid. Then it will need to be bleed if you don't know how it would be better to take it to a mechanic. Let me know if you want to try it and I will help you.

Check that on your carburetor, when you press on the throttle, it still shoots a little bit of gas out into the barrel. If it does not, you may need to replace the throttle pump. what is happening is this: As the throttle is opened higher, the vacuum drops severely, and the fuel doesn't get put in. The throttle pump pushes a little squirt to retain the vacuum. If it is an EFI unit, you have other issues, that I would recommend a mechanic for.

Guages on 87 rx7 gxl dont work


I'll help with the brake lights. 1st check fuse, 2nd there is a brake light switch located at the brake pedal you will need to get under the dash & find it. Remove plug from switch & bridge plug with wire If the lights come on the switch is faulty (have the ignition on while doing this) 3rd check brake globes it is possible all are blown.

My 1987 Mazda rx7 has a problem when trying to accelerate. When I press on the gas pedal, it sometimes feels like it's going to stall. Some days are worse than others.

If it does not, you may need to replace the throttle pump. what is happening is this: As the throttle is opened higher, the vacuum drops severely, and the fuel doesn't get put in.

83 Rx7 stalls when cold unless I keep applying pedal pressure


these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.

Have a 1985 mazda rx7 will not idle .. cold start ok when choke is on once warm stalls and will not idle


There is a throtle adjuster right behind the carb. You can adjust it with a screw driver. If you are not sure where it is, just have someone press to gas pedal and you will see it move. RPM's at idle should be around 1,000 when it is idle once it has warmed up. Once that car warms up the choke moves back in and the car is probably stalling because it is not running enough RPM's.
