my car is bogging like crazy and acting like i have a vacuum leak cuz it can barely idle and when i rev high enough it dies

pressing the gas pedal while the keys are at II on the ignition yields a solid CEL

any thoughts

no vacuum leaks from what i see

If your vehicle has a solid cel with no srs jumper & with a srs jumper in place, then your ecu is not working properly.

neptunes bee running for a while...
and cel solid only when i check codes

check your map sensor.

i did...FYI im running a 3bar map sensor
strangly enough... it sounds like a bvacuum leak...
i removed all lines going to my vacuum manifold, only hooked up the map sensor and plugged every hole in the intake manifold....

stil happenes...
map sensor does see vacuum, from what i see in my datalogs..
but my boost gaujge shows some leak somewherei think (less than 20 inHg vaccuum)

pcv hole plugged
brake booster hole properly connected
cruises control plugged
EVAP purge solenoid plugged

i didn
t save the datalog, but here is the map sensor read out with a couple other things..

i know this has nothing to do with the ecu, but is it possible that your timing belt jumped a tooth? also, what about something inside the distributer going bad?? icm maybe?

i'll have to look...

bump for any other ideas..
i have been busy all week, but here is what i will check
timing
vacuum lines will be revisited
possibly creating a boost leak tester.

any other ideas will be appreciated!

my friend with a DSM had an idea... does neptune run its maps like a maf setup? (i.e. would a blown off charge pipe do this like on a DSM?)

HRTuning

No that would not cause it, you are not running a MAF.
