I just did a swap on my EF (crx) a b18b1 but the **** is that my check engine is on (yes i connected everything) and when I rev my engine it gives out at 3500rpm Im not sure what could it be I tried different ECU's but nothing. One of my homies told me it might be the throttle sensor (and well the thing is that since i put the motor from under well the engine leand backwards and it cracked the sensor's plastic cover but it still clicks when i connected.) Anybody haves an idea of whut is happening if so let me know plz I would appreciated.

thanx!

 

What is the code? Sounds like it's in limp mode (solid cel).

 

check the timing

 

try a known good distributor and double check your wiring.

 

its not throwing any codes the light just stays lighted, and whut is limp mode???

 

Limp mode is what happens when something is fucked up bad. If the light stays solid and gives no codes that's a solid cel, which means dead ecu or bad wiring somewhere or something similarly bad. If the ecu is known good start checking your wiring.

 

Hey guys new to forum, but I'm dealing with the same situation 1991 crx si with b18b1 ls pr4
build went good then after 2500 miles . till I had experienced a situation where my brake booster built up to much vacuum or something to the degree. Causing the brakes to be applied without knowing. car starts to get hot but not but 25 to 30° past oem honda standard.. after getting car home and starting the next day it was in a 3500 rpm limp mode.. I will try and lend a hand with information thanx guys

 

any codes showing on the ECU? most of the time, going into limp mode is a problem with the distributor

 

It does hav some codes . I will be documenting this ordeal the best I can so it may benefit others. I only go to my shop on weekends at my dad's house so it will be a week friday or Saturday before I can get back on it

 

Iv owned ef models and crx models from the start in 2006 wen I first got my dL .. but thus one needs help it's a chop job of improper wiring I will get back thanx

 

And for sure getting new dizzy the car was converted to obd1 by former owner and wen car was parked it got striped of the obdo-obd1 jumper harness dizzy and ecu . So the guy just threw stuff on it to get the car sold I anyways till next time

 

Does have codes I now it was previously converted to obd1 but everything was converted back leaving a wire loom mess. Its definitely not solid cell, it is throwing code I'll get codes this weekend and post my findings.. I appreciate and help ben a few years off the honda horse lol

 

You don't need a shop to pull codes for you. You can do it easily.

 

Miss understanding,, I own the shop where the car is located it's my personal shop for my and frends cars .. and no lie about taking the car to a paid shop wen I can read the codes. I just have to wait till Saturday with a good battery to put on can , I'm just happy it's not a solid cell and the pr4 still throws codes

 

Also check for swapped sensor connectors, which is an easy mistake to make during the engine swap.

 

Good looking frend thanx

 

I will definitely post some pictures of the car In its condition as I bought it. This is going to be a workout but worth it

 

I've had the same issue and it was the TPS.

 

just posting some information hope every one is having a good day frends,,, I am growing to my shop shortly and will be recording the codes for honda -form if any wone will take a look .. I I will be back later today to give up date thanx honda family

 

Ok guys soo I'm really stoked at the situation I'm at shop ran codes 4 came up (24) (3) (7) (8)
but I messed with wiring for a bit before chasing the codes and car runs now with no limiter at 3500
