could be... having your injectors cleaned and balanced for about 100 bucks is the best way to gain 5 hp you can come across... no im not ****ting you... 5 hp..

 

hmmm.. well theres a place down the street from me that does that, now what if i do that and thats not the prob, then what can it be.. im so stumped?

 

k got the injectors cleaned and nuthing, but this is what i did... i took the first 02 sensor off, when i drove like that i had no power low end but it took off like a bat outa hell after 4 grand, but i would leave it like that but it keeps boggin out on me, now i had another 02 sensor laying around and i pluged that one in cuz maybe i thoguht it was a better one but same thing... so i pluged the old one back in and same results as b4, i had good low end but no top end... ughhh idk what ta dooooooo

 

Have you hooked up the downstream o2 sensor yet???

how about checked for leaks around the exhaust manifold...

maybe your plug wires are starting to go bad... like its good enuf so it runs ok at low rpms but at higher the signal brakes up...

 

my car has a ruff idle and low end deficiency problem and sounds like it has a miss below 2500 rpm and above that it runs great any ideas?

plugs or wires?

 

nither cuz i bought brand new ones 4 days ago, i thgouth it coulda been a fuel problem.. how bout a knock sensor whats that cuz i didnt replace that thing yet?

 

hey guys would the first o2 sensor have anything ta do with it? even tho its not reading a code?
