well i took off the gas tank and turns out it is in great shape. so i took of the gas lines and blew them out one by one and got another fuel pump just in case the one i had was bad. i know it cant be the cat becuase i released the beeds or poured out the lead pellets inside it a long time ago i was wondering if any one had any other ideas cuase i am trying everything here and nothing is working. trochoid could it be the performance wires i put on?becuase that is around the time the problem started.

 

never mind i FIXED IT!!!!!!!!!!!!!!!!!!!!!!!!!!! hahahahaha it was the cheap *** spark plugs this whole time. man i was happy when i figured it out but then pissed cuase of all the work i did, but it turns out the carb i had on before was bad anyway, and ****! now i know i got a good fuel system, but hey thanks too everyone that tried helping by giving me ideas.
much appreciated.

 

Typically a clogged cat bogs down with heavy throttle inputs ie high volume of exhaust cause back pressure to rocket. Thus bogging down an engine. And his problem seemed temperature dependent, I'd think a clogged cat would be a continous deal.

 

Guess some things shouldnt be shot down so quickly. Anyway its great that you got it going.

 

ok check it out i got rid of one problem and found another. i cant get my inspection becuase my lights wont stay on when i turn the high beams on but if i pull the lever back then they get brighter like there suppose too what could be the prob.

 

The contacts on the dimmer are likely corroded. Many people have had success by disconeccting the battery, and spraying electrical contact cleaner into the dimmer, and working it back and forth. If this doesn't help, you may need to disassemble it, and use emory cloth to clean the contacts.
Of course, you could always just fake out the inspector by pulling back on the dimmer, and holding it.

 

Headlight fix = https://www.rx7club.com//showthread.php?t=441702 Keep in mind that after I wrote this, it was discovered that usually you can just use the nozzle on the can to reach inside the switch without any disassembly needed. Good luck.

 

well i got all the problems out of my car and did some other stuff like i took off my a/c unit and got new tires and also i put a 9 psi fuel pump with a fuel pressure regulator. i took it to the track and ran a 17.328 is that good???

 

what do you think of a racing pully after i take off my air pump and put on the block off plate. faster/ the same/ or slower???

 

hold on! so ur saying if i remove my emmissions includins air pump and have a cat its going to eat the honey comb in the cat???or melt it???also my cat is weird, i took it off the other day to replace a gasket and it doesnt have honey comb, it has like a metal shet in a long upside down 'u' i gto it from mazdatrix if it helps.
