I got out onto the highway and my 83 rx7 won't pass 65mph. I've got the gas pedal down to the floor. This sucks can anyone tell me what the problem might be.

 

Check the following:

fuel filter

air filter

tune-up (plugs, wires, cap, rotor)

and... if none of that works, then your cat is probably clogged.

 

I'd have to go with your cats being clogged. I have an 85 and cant get past 80 so I know how you feel. I have also just done a tune up, new NGK plugs,wires, cap and rotor, air filter, fuel filter and none of that cured the problem so now it's down to the cats. Just gonna get the cat replacement pipe from racing beat.

 

im gonna check the following which you guys have posted, but i bought this rx7 and i've checked that it has no cat its just the straight pipe coming out from the manifold to the muffler. thanks

 

take your plugs out one-by-one and hook them back up to their wire. Then crank the engine to make sure they're all firing.

 

check to see if yur secondaries are opening properly?


also u knwo that housing that the spring is in.. that has to be air tight..

bolt those very very tightly.. make sure no air is gonna escape..

if u have to put those liquidy gaskets around it.. so be it.. make sure its tight..


that helps

 

ok i got a quick question where are my secondaries. Please describe where or even maybe a pic. what about that housing spring thing.. I also might have a suggestion does anyone think its my fuel pump because its the original 81 factory one that i swapped to put on my 83.

 

where in AZ are you at, i mIght be able to come out and look at it.

 

Another thought... look on the passenger side of your carberator. (take off the air cleaner first)

As you are looking at it, look at the bottom left hand corner of the carb. You will see a pivoting bracket with a big spring on it. There should be a rod with a cross-brace on top of that pivoting bracket. It frequently falls down. Pull it back up with needle-nose pliers.

 

Look near the bottom of my page for pics of this.

ok so that spring opens the secodaries right??? i think i might have an idea on what your talking about.. Oh yeah im from Douglas, AZ. right on the border of mexico..

 

Nope, those are you throttle return springs. The one that like to slip off is a back up spring in case the main one breaks.

 

ok now i understand thanks. im gonna check it out as soon as i get the hell out of school.
