ok so here is the run down 1990 crx hf with a jdm d15b with a po8 ecu (obd1) will not stay running as soon as i take my foot off the gas and bogs kinda when it does idel then the del will come on idel will come up and it just kinda spudders and dies.... so far i have replaced my Iacv (idle air control valve) new cap and rotor, new plugs and a new fuel filter but still does the same thing right now its throwing codes 5 and 13 5 is my map witch the car has never had so it eleminates that next 13 is the atmospheric pressure sensor according to some guy on line that is only on the edm d15b? idk help?

 

your car does have an atmospheric pressure sensor (PA), however, it sounds like you have a vacuum problem with the MAP sensor - fix that and the code 13 for the PA sensor should go away - are you using the MAP on the throttle body of the D15B or are you using the MAP on the firewall for the HF engine? - my guess is that you have the connector still plugged into the MAP on the firewall and that you don't have a vacuum line running to the MAP - you should really use the MAP on the throttle body, which will mean you need to unplug the MAP on the firewall, put a different connector on and plug the connector into the MAP on the TB

there is a map on the tb but no plug going to it and it has never had one .... and ran fine before where is my maf located on the fire wall? pics would be great also pics of the vacum line would be awesome and the strange thing is i took it for a short drive and stoped at the store car idel was fine went inside came out was still running fine then i started to go again and problem is back

 

the MAP on the HF is inside the black control box on the firewall - you need to run a vacuum line from the intake manifold to the MAP (hose 21 in the picture)
