Start noticing hard shifts recently, car just got to 30K
rough idle, low power at low rpms. Code reads Random Misfire. I have been told the lost compression in 2 cylinders is the culprit and a valve job is needed.
93 miata flooded during hurricane. now cranks fine, but immediately chokes down once you get it the gas to go. computer gives no indication of any problem. Mechanic has run out of options. Any help would be appreciated.
Having no problems,would just like to know what the little box is for
I replaced thermostat coolant fan relay and temp sensor ran a block test came back clean no blown head gasket or cracked block. Flushed the radiator out car still overheats after sitting at idle for 10 mins the radiator fans will not come on unless I turn the AC on I disconnected the upper radiator hose with the car running to see how much pressure was being put through the radiator and the water or radiator fluid from the vehicle was barely dribbling out of the upper radiator hose and the engine was hot and the thermostat was open
Starts and runs fine when cold. Will start but not run when hot. Gives codes 1 and 8
The drive shaft broke got it and back housing to transmission fix but speedometer stop working and it won't shift to second unless I do it manually
I have a 92 MX5 and the running lights do not work, but the headlights and brake lights work
the fuses and bulbs are all good
What do I need to check?
Beams simply seem too low. There is an annoying shadow line about 4 feet off the ground at about 25 - 30 feet on low setting and highs only seem to illuminate well out to about 40 - 50 yards.
I have one that did not go back into the hole of the automatic transmission filter, what could be the problem and what can I do to correct the problem
Low Beams At Half Mast
Hi, I just bought an '08 Grand Touring 6spd and the first time I drove at night I noticed both low beams only illuminated about 40' out, both are equally powerful and equally aligned. At 40' there is a definite, straight, horizontal demarcation line between light and dark. The high beams are perfect. The car is too dangerous to drive at night. I know this probably doesn't relate but seller just replaced battery so car had no electrical for a little while. Is there anything on the car that would have to be reset after that? Can anybody help? Thank you in advance.

I need to do a tune up, the rich running an O2 sensor problem and how many are there in a 1990 Miata?
My 1.6L over heats really fast when I do just normal driving as well as just sitting, it's also started to make a new squeak just before this happend it leaks coolant as well but very slowly and I had just filled it about a month ago, I haven't had the time to really look into it cause of work, any suggestions on what to check? to make my life a little easier, thanks
Car runs great, it just seems to me that in fifth gear at 70 MPH, 32K on the RPM is a bit to high, am I wrong or is this normal for this small car? I'm used to my Chrysler "grocery getter" mini van lol.
2006 mazda mx5, 50,000 miles.
Engine light came on 2 weeks ago. Checked code and it comes up with the knock sensor, wiring, and ecm.
Wiring is too new to have any problems and there shouldn't be anything wrong with the ecm or a different code would come up for that. Tried locating the knock sensor and I can't find it. Like I said, the engine light comes on and goes off same day or every other day.
Also, I've been having some hesitation in power when applying the throttle going into 4th gear.
