Heres the deal, I just finished my turbo install(still need clutch and flywheel and then tune) BUT when i started it and let it warm up the cars RPMs jump up and down. Before winter it was fine, now its jumpy. I did replace the timing belt BUT i thought i didnt move anything. Ive been driving the car for about 2 days and put mabye 100miles on it with the turbo. My Oil pressure gauge jumps up and down too. WHAT DO I DO?! Should i be worried? Should i just wait for a tune on a dyno? Why would it jump up and down like this? Also i might try and do the timing myself…if its easy but what should the RPMs be set to…800 idle? ANYONE? PS-1995gsr B18C1 ---

what did you change in the ecu? what are you using to tune it with? obviously, you changed something in the fuel system, so that’s different. ---

my ecu was reprogrammed using chrom by a innovative. could it be a vaccume leak? or just need to get tuned on the dyno? i was just given a basemap so the car would start up, tuning later. ---

hunting idle could very well be a vacuum leak. ---

and how to find it? i heard you just spray water on vac lines and look for bubbles while it runs. I do have a Greddy type RS BOV-many peopl ehave said they leak at idle and many have said they dont. can this be adjusted if this is the problem ---

noobs, check your iacv valve. pull it off, clean it with carb cleaner and reinstall. Its a VERY common honda problem. ---

the injectors should not be a problem as long as your tune scales for the bigger injectors ---

if its just a base map its very possible that the fuel table for the idle section needs work. mike and i had that issue last week with a car.
