is it really loud? make sure you didnt blow of some intake plumbing..

 

Do a compression test.

 

yep, im having the same problem and my rx7 is non turbo..

 

^^ N/A .. that doesnt sound good.. check over every thing in the engine bay and make sure its in proper order.. maybe you got lucky.. i guess.. and both the spark plug wires fell off a rotor or something stupid.. or maybe you ran out of gas..

best thing, like Stanello said, is do a compression test..

 

run a compression test and look for vacuum leaks
