could it be bad compression?

 

update... my oil has a vas smell.. so could it be leaking injectors

 

Go back to school and learn how to spell. After that, these could be your issues:

1. Spark plugs
2. Spark plug wires and boots
3. Boost leak
4. Dirty MAF
5. Bad tune

 

im on my fn phone..but thanks for the input

 

bump........

 

could it be my fuel pump. it is stock and i just ht 90k.

 

I would try to diagnose stuff first before just throwing parts at it. First I would make sure nothing obvious is the cause, dv installed incorrectly, hose clamp loose, hose clamp over torqued causing a hose to be out of round (boost leak), loose or damaged vacuum lines. Second, do a boost leak test. Thirdly, check condition of your spark plugs, coils and connections. Remove your intake and inspect your MAF. If its oily, that may be the cause as well.

 

thanks for that but i have check and check all clamps ..dv.. everything u said.. and im trying to find out how to do a boost leak test... but this search sucks. Thank all of you for your say.

thanks man but i found it...thanks anyway. i used google

 

did a boost leak test today.... there was a leak by the licp.... but by the throttle body.. it was loud hissing...got some mil spec seals.... but its still bucking. i also did a compression test.. 175 for all.

 

No, I doubt it. Make a boost leak tester, I think you have massive boost leaks.

edit: Sorry, I didn't read page 2. It could be your SAFC. My car used to kind of buck a bit under load with an SAFC, so I took that piece of **** off and it runs great.

 

you have all those mods and a stock 8 fuel pump? has this car ever been tuned? what are your plugs gapped to?

 

+1. I was thinking the same thing. Perhaps a fuel pressure test is in order after the simple things are tested.

 

ill get on that asap..i think i found the problem....ill get back with yall.
