because the hp calc tells me the hps 101 hp with mods... 131hp divided by 4 would be 32.75 times 3 would be 98.25 with the mods would be with the 3 cylinders 101... could 1 cylinder be off or misfiring? could the injector be broken or the spark plugs be busted? or could the piston ring be jack off?

if you got any of the above problems then you will be suffering from more than just lost power... i recon all your injectors are a bit clogged or not functioning well, how old are they anyways??

also this can go for the spark plugs and/or spark plug wires.

71 but there tends to be some kind of piston slap or rod knock... the piston slap test worked so theres possibly piston slap

chances are your injectors are clogged... try to get them checked and clean them up, i would have saved myself the hussle and replaced them.

from hp calculator... do u recommend throttle body cleaner or fuel injector cleaner or both?

MMamdouh · Post by **MMamdouh** » Mon Dec 05, 2005 9:51 pm

i recommend both... dirt is a HP eater so you got to keep evert thing clean.

check your air and fuel filter, throw in an injector cleaner, clean your TB and intake with WD 40 or carb cleaner... personally when i cleaned my intake the car felt faster.

yea... will do that later... throttle body cleaner would work wonders? putting on the lucas fuel system made my car run bad...

If you Leggy is not running well, you shoud start checking the following before jumping into conlusions:

- check the condition of the sparkplug, and ensure you have propper gapping. From my experience, we use simple NGK V-groove plugs for all performance and boosted apps. They are inexpensive and work well

- if you had never replaced 02 sensor do that. The Injection system on Leganza depends heavily on these, and if you get incorrect reading, the motor might be getting either too little or too much fuel, causing reduced performance
- replace fuel filter
- add fuel injector cleaner to the gas
- check the spark plug wires
- check all the vacuum lines

Installing higher flow injectors will not make the car run better. For about 150 crank horsepower, you would want to use something in the range of 22-24 lbs/hr @85% duty.... anything larger and you will not see any gains. Remember the injector size is matched with the horsepower...

Hope this helps.
