Okay i took my civic out for a drive today and when i start to go it almost dies and i throw a #3 light (MAP sensor) thats when i'm not even boosting.. when i restart the car and hit boost it won't throw it unless the rpms drop... and now when it's at idle the car goes to like 400rpm then back up to 1000.. and it keeps jumping

what do you guys think it is

Whats your setup and what fuel management etc. are you using?

draztik

DSM 450cc injectors
V-AFC at idle its at -42% so it should be getting enough fuel and yes i tried it at -48% also and same type of idle.. it just won't stay at a certain rpm.. like i even upped the idle to 1500 and it dropped to 600rpms and back up to 1500...

also the car was sitting for 6-7 months could my MAP sensor have gone to ----?

and i'm on the RHB5 and full boost is 8 psi but it don't even go on in boost, just when i'm starting to go and it almost dies than i have to rev it up to 2k and let the clutch go just so i don't throw the CEL

Oh yeah 1 more thing... when i start to go VERY SELDOM the CEL comes on when i'm getting up to speed then it goes right off.. in NO boost too.

Hmmm, did your battery go dead or anything after that 6 months of sitting there. Check to make sure that the "vehichle settings" are still correct. It should be the arrow facing up at a slight angle, and 06in-06out.
Also, is there fresh gas in the car? Could be bad gas now that it's been sitting for so long. I'd also start checking over all my wiring and vacuum connections... Mice like to chew copper in wires

yeah my battery dies.. so i have to disconnect the battery everytime i go to start the car... but i remember i checked that setting and it was still 6/6 a while ago... maybe that was when i just jumped it and looked and still had the battery connection.. maybe by disconecting the battery it'll make it reset? i have no idea.. yeah there is fresh 91 octane pump gas in there...

could it be the MAP sensor for sitting so long without starting it, 6-7 months..

im going to go on what my gut is telling me....its the dead batt., is like when your batt. dies and you have to re set your clock and radio

draztik

well all the fuel correction points are all the same on the V-AFC each time... not unless the in/out deal would only reset? i'll check to see if thats it tho

double check all your vacuum lines, if you have one loose it will ---- your ---- up real bad

draztik

okay i'll recheck the vacuum lines... BTW i LOVE boost!!!!! psi and my turbo is loud as ---- when it spools.. my friend was like 1/2 block away and he said he could still hear my turbo.. haha

check your wiring connections for the afc at the ecu.
