SR power problem

[keMz]

compression is 150 across the board
plugs spark
fuel filter is g
fuel pump is g

it starts up and then idle drops and dies..

it revs but once u let off it drops and dies..

anyone had the similar problem??

its a s13 redtop fb...

THANKS FOLKS

sounds like air problem. check vacuum lines, maf, tps. will it drive at all? That sounds like a wicked vacuum leak.

Check MAF, Vac/Boost leaks,timing and ECU for codes

like clean maf or what and how do i check for codes..

idk i died like 2 times in a row then it started acting up and drives but u cant go above 3k with out it acting ruff

Trying cleaning it, but better to borrow a friends SR MAF or SOHC KA MAF
to just test it

TPS and/or Temp. Sensor interchange, anyone? let's not hijack this.

- this is general for 89-98 Nissan but most apply to the SR20 motor.
- to set car into diag. mode, with the key in the "ON" position, turn potentometer screw on ECU fully clockwise, then turn it fully counterclockwise. The LED on the ECU will begin to flash.
- first digit = LONG blink; second digit = SHORT blink (ex: 1... 1... 1... 1... then 1-1-1 equals 43 = TPS)

k il try check it out..

it runs and maintains idle but exhaust pumps black smoke, then when u try to drive it acts ruff..

it drop good for 200-250 miles after rebuild then day 2 when we go to cont break in, this happens
