Hi, check engine light requires you to have the engine CPU scanned for trouble code's. This can only be administered with the assistance of a diagnostic computer scan tool called OBD 11 scanner. You canpurchase this tool, at your local auto parts store, or you can just have the scan ran at your local auto zone parts store, free of charge. Once the diagnostic scan is administered, you will be able to isolate the issues that have caused the check engine light to illuminate.

This scan tool will display a print out code and the location of the issue, on the engine, as well. There are Many issues that will cause the engine light to illuminate, but the most common cause will be a failed monitoring sensor, or sensor harness failure (separated power wire, or ground e.t.c).....


You definitely have to carry out the scan to know the cause of the problem.

I have a 1989 mazda rx7 convertible automatic with the 13b rotary engine and im going to swap the engine and tranny for the 13b turbo engine and manual tranny,and also have ecu.is it hard to swap and how.


its not hard at all. as long as your good with your hands. and know the basics of your rx7. other then that everything bolts in. you just need a turbo driveshaft for sure. or they sell a custom driveshaft on mazdatrix.com so you can keep your N/A differential.

1989 ford f150 w/ 5.0 liter..... engine light on


I would check the oil pressure of the engine. The reason is the timing chain tensioners are run with oil pressrue. I think your timing chain tensioners are leaking down when engine is getting to operating tempature . The oil is thinning down as warms up , as it should to lubercate . I would check compression and do a cylinder leak down test on all the cylinders. Then if the compression is good and the cylinder leak down is good. I would change all the timing components, ( chain, timing gears, timing chain tensioners )

Good Luck , I hope this helps.

87 RX7 - smoking exhast for several miles then stops


well,when you turn off the rotary it leaves oil and gas.so when you start it up, it burns off the oil you left causeing blueish smoke. same problem with flooding,when you drive short distance , warmup incorrectly or if use synthetic oil.to fix the cause of flooding(i have the same vehicle and problems)let it warm up for at least 15 min.there is also a fuel pump wire next to the fuse box located above the brake pedal.then you tap a switch from the fuel pump to your interior.the reoson being is so whenever you come to a stop to park flip the swith.that allows the rotar to burn the fuel left in the pump witch will make your rx7 to stutter out and die.when you start it back up ,flip the swicth back on and it will take an extra second for it to crank over.1 more thing,check your oil every 2-3 fills on gas and change oil every 2000 miles.also redline it at least one a week. i hope i just solved your problem because i love my 87 non turbo and know how you feel.if you want to look at cheap aftermarket parts for rx7 then go to srmotorsports.com/rx7guru.com is a guy that test parts to tell people wats good and cheap for rx7s.i would recomend roll cage and 5 point harness-seats.good luck with your rx7 bro
