I have a 95 se 5 speed and live in denver. I have tried everything i can think of and have read on this site to help without resolve. Ive changed my plugs, fuel filter, knock sensor, air filter, coolant sensor, cleaned my throttle body more times than it needs im sure. Ive adjusted the throttle cable, run the recommended 91 octane highest you can get in denver. Am i missing something??? It seems as if its running on four cylinders, but idles and starts fine. Gas milege is decent between 275 and 350 a tank. However when im driving and try to accelerate it just doest have the jump it should, and feel really sluggish. And there are no codes at all. Any ideas?? Thanks for everyones help in advance.

 

go get a heynes manual and test ur O2 sensors in the front

 

I did a overhall of my egr system gained good power and all of my hesitations when away. Mainly cleaned ,sandblasted and acid dip.

 

Yeah, O2, and why haven't you checked your coils already???

 

Try some BG 44K fuel system cleaner.

 

dyno the car.

 

Thanks to everyone who replied. I have checked and replaced the coils. I will check the O2 sensors havend had any codes tipping me off, can one be bad and not send a code?? I have tried fuel injector cleaner 44k, and similar others as well. How would I dyno my car??

 

i have read about o2 sensor got triggering the code bacause it is partially working, check hte voltage nad stuff on them

 

check the voltage on your MAF w/ a multimeter.. people say that low voltage on your MAF will cause major lag
