I've got a problem with my 83 rx7. The car won't pass 80 mph. I've got the gas pedal down to the floor and it just won't kick in any faster.. I can't even pass cars on the highway because i won't go fast enough to pass cars.. so if anyone has had a problem like this please help..

 

maybe you have clogged catalitic converters, I know my top end power was greatly increased after i took mine off.

 

need a little more to go on ... how long have you had you car and how long have you been having this problem? any mods? when was the last full tuneup?

for now, all i can think about is that maybe your secondaries are not opening.
