94 Mazda 626, 2.0, standard. Installed a used throttle body and idle air control valve, new plugs and wires, o2 sensor, fuel filter, air filter, distributor cap and button. I took apart the IAC and cleaned it. I'm pretty dog gone sure the springs and etc are correct. When I try to start it, it only starts on second and third try and I have to pump the petal several times for 5 seconds plus to get it to idle. It has hesitation when petal is pushed. Biggest thing I noticed was a strong smell of gas/fumes out the tail pipe but after 1 hour of trying to adjust timing by ear the new plugs and o2 sensor is covered in black powdery soot. I also noticed that when I put pressure on the throttle-spring on the throttle body where the cable goes in the opposite direction ( as in thing to close it more the car seems like it will idle better. What could be the problem and what steps do I need to take to start eliminating and checking the problem. Thank you

I have a 1991 Mazda 626 5 speed transmission and i ran the motor to let it get warm, i pulled the oil dipstick to check oil level and oil mixed with water was spewing out of dipstick?

There is gas in it and it just hit 2000 miles. This is the first time it happened. No check engine light is on and checked the spark plugs already

I have a 2002 Mazda 626 with a recent coolant leaks. If I maximumly fill the tank with fresh coolant, the leak is very slow, probably 1/10 per week. If the coolant level is below the half level, the leak is very fast. What is the problem? Thanks.

This is a manual trans. The handbrake problem seems to be near the handle at the console, and went from half-working to not working at all.
The cruise control system seems complicated, and has totally stopped working a year ago. Can you supply instructions for diagnosing/repairing these systems?

I took the car to get an oil change and when i got back home and turned it off and tried to start it again it will not crank at all. A friend told me to replace the main fuse under the hood and it keeps blowing. Could it possibly need a whole new positive battery cable? Thanks in advance.

I need a yearly emission inspection

parked the car ,smoking blueish out the tail pipe ,ever time i drove still smokes until sat it run for about 20 mins no smoke at all and yes it has oil in it ,not running hot still has power what happen

I replaced the crank pulley and in order to keep the engine from starting I unplugged the coil pack. The engine ran just fine before I unplugged the original coil pack. Now even with new coil pack I get no spark. what could it be?

the car has been sitting for about 8 months

The vehicle has not been running, for about 9 months now. During that time, I have replaced, the fuel pump, starter, the distributor, distributor cap, rotor, spark plugs & wires, alternator, and battery. I sent it to the Mazda dealership, for a recall, on the ignition switch, thinking that might have been the problem that I've been chasing, but had not shown up on any prior diagnosis. The vehicle has now been there for 2 months. That's to get the ignition switch put in. And once the car still didn't start, they began a diagnosis. How much should that diagnosis cost me, being that so many parts are already new and working, that I'd replaced. I'm being told, that they will have to charge me per hour the diagnosis cost to continue to search for the problem. Is there much more that could be wrong with the vehicle, other than what's been replaced? I'm being charged now for 2 hours of a diagnosis. About 250 total, however they say, that they have put in about 4 or 5 hours worth of time, so far. It just seems that there should be a ceiling price for a diagnosis charge. If anyone can help me with an answer, I'd appreciate it. Thanks.


Key is spare not the original key turns over will not fire

I'm installing a remote start system in my car. The remote comes with a trunk release button. Where would I find the cable I need to connect to in order for this to work?

I have canister that is labeled fuel pressure valve in the only diagram that I could find with it in the specs. but I can't find that anywhere I search to find a replacement part. found the tank and everything else. I broke one of the hose connection tubes and need to get another so I can finish reinstalling the tank now that I've finish replacing the fuel pump and have the tank ready to go back up

The coil tested "Good". I replaced each component piece by expensive piece. Then replaced the coil , it started right up. Both coils tested the same w-a meter, no shorts , no opens . Try a coil , don't trust test results ! ! !

Not blowing cold air

What would cause no spark from coil ?coil is good

My car has a problem when in gear. It drops idle every once in awhile to ~500. If this is the BAC please tell me what to do. Thx.
