Ok, have a 00 ex with stock d16y8, used to have p2p ecu. Now a chipped p28.. The problem is it has a hard time starting, at 1500 it acts like a 2 step, and kicks while driving.. I put the p2p bk and 1500 start up idle. When running codes the p28 said 14 (iacv) and p2p 170(system too lean) so im guessing iacv but what do u think? And will myecu(p28) power iab? Does mine even have that? Sohc vtech.. I know f.....n noobs

Nvm the last part. I'm dumb... Still need the help with the 1500 2 step. If I cover the throttle body, it still runs? Wtf? I've checked all hoses, replaced gaskets and replaced iacv.. im out of ideas

You have intake air (TB or IM gasket) or vacuum leak (IM nozzles/hoses).

Did you torque the TB and IM bolts/nuts to spec? Any disconnected vacuum hoses?

Did all that, and sprayed Carb cleaner looking for an idle jump, but nothing..... I've replaced intake gasket tb gasket pcv and im running out of ideas

If you cannot force the engine to stall by blocking the top of the TB, then by definition, there is a substantial intake air leak (TB or IM gasket) or vacuum leak (IM nozzles/hoses).

I know, it's driving me nuts. How easy is it to crack an intake? I don't have any other ideas. Gaskets are all new.

All hoses checked out too...

Gonna try siliconing gaskets. Maybe thatll fix it.. I can hear a faint leak sound coming from the intake... Somewhere.... I emptied 3 cans of carb cleaner and the old follow the smoke trick...

Did all that and No change... If some how the canister that holds the pcv got cracked would it do this?
