My car is a 92 CX hatch with a B16A3 from a 94 Del Sol Vtec, ECU is 38720-pr3-j01, and I'm using a harness out of manual trans DX(pre-wired for 4wire o2) I added the wires for vtec and knock. I did the swap myself.

My problem is that it acts like it's in limp mode but no CEL. It's not hard to start except I have to work the throttle to keep it from dying initially, then it will idle fine on its own(if a little low). When I give it gas it hesitates like it's out of time(its not). I can get the engine up to about 2500 and the fuel cuts out until the rpms drop.

I've been thinking it's a fuel issue since there isn't a CEL. I hooked up a pressure gauage and read 34psi and it drops a couple psi when I turn the throttle. I still need to check volts on the ecu but I have noticed the connector for the evap purge solonoid has .3v but again, no CEL lol.

I also want to add that it ran pretty much great for a couple days in the driveway. I drove a very excited 50 feet when it cut out and this whole issue started.
Just wondering if someone else has had this issue and knows the easy fix lol. Or at least where I should focus my efforts. If more detail is needed Ill be happy to respond to specifics.

Thanks in advance

 

 

I'm almost embarrassed to admit but I figured it out. I had the tps and map connectors backwards, oops. Easy fix at least lol.
