This is really getting annoying i have had the del sol for about 2 years now and did the swap little less a year ago.

Ever since the motor will not rev past 4500 anytime it is past half throttle anything below that it will rev till about 7200 and tranny doesnt like it.

Every thing i replace is no help the compression is fine and i am using the p13 ecu
so far i have replaced the o2 sensor and its currently disconnected (runs better that way?) dizzy, fuel pump with a walbro 255 lph, iacv, whole throttle body with one from f22 or f23 not sure has map sensor located on top, and i am using the del sol wiring harness.

i have lately noticed that it will run rich during idle and low throttle and lean when in heavy throttle.

any suggestions would be highly appreciated

 

this prolly isnt the type of suggestion youre looking for, but b18c bolts right in, easiest swap ever.

 

when i put the walbro 255 in my h22 car it also ran rich and i noticed the fuel pump will bring the fuel pressure up about 8lbs. i'm sure that won't fix your 4500rpm thing but maybe it will be of some help.

 

changed the ect sensor now its hitting vtec at about a quarter to half throttle at the appropriate place, but still has the same problem while above half throttle. kinda running real hot. the egr is out and blocked off and knock is unhooked. any ideas and or suggestions. and yes i know a b series would of been easier but it would take boost or some motor work to get where i am at.

 

Is the ecu chipped? If not, why do you have the knock sensor unhooked?

 

try a different ecu.

 

i have tried a hondata ecu still did the same thing . it came out of a b16 del sol and it was actually made for turbo though also tried stock p72

 

installed new radiator and thermostat. seems to run a lil bit cooler (heat aint rollin in the cab now). the other one was too small jsut single core del sol stock now i have a double core and the barely shuts because of it any suggestions on that because engine doesnt hit just radiator.

going to replace fuel pressure regulator when i get back from virginia (job) no fun)
will be back fri. or sat.

thanks for the help

 

lol im willing to bet its your tps.........even if it doesnt throw a code and still works....the degrees are probably off

and slower

What CEL codes do you have?

 

the tps could be part of it but it will only mess up while ideling. mine was brock and i had none of the issues that you are having. check all you wiring and parts to your fuel system

 

no one asked about injectors.did you use the original del sol injectors. the injectors may be too small. you would have to bring the car to someone who has the ability to reprogram the ecm while looking at the afr.

lets not forget about the resistor box!

no injector resistor box = obvious problem. (would the car even run??)

There's got to be someone from WV who can help this guy out.

 

HOLY ****, this post is fairly old.
