<![CDATA[CRX SI swap questions?]]>Well todays project was swapping my old HF engine out for a SI engine and transmission. But I don't know what vaccum lines to use and where to connect them, can anyone help.

I got the car running now and when you step on the gas it hesitates and then revs up. Any ideas?

I am also getting a check engine light, anyone know what the codes are?

I figured out my check engien code was a TPS sensor, and I noticed that I busted it putting the engine in, so I just swapped it for the extra I had and all is good.

Now I just need a intake cause my HF one won't work and the exhaust needs to be redone because it is too loud.

No. There is no vtec with either engine.
