I have a 1997 Honda Accord LX 4dr F22b2 engine. Well my car was always running like **** after getting it tuned and today I decide to check everything and see where the problem was from. We figured out nothing and it still runs like ****.

Alright first the oil was changed then I decided to check the engine by pulling out the spark wires. After pulling out cylinder#1 the car didn't change so that was a problem and same thing happened with cylinder#3. So something was really messed up. The other 2 were fine because the car felt like it was gonna die. So next we changed up the spark plugs to see if that was the problem. Still same thing.

Next we did a compression test.... this is the weird thing.... it read 175 all the way across. How is that possible? Then we think it might be the injectors, so we check them with the light to see if they are getting power and bam they are. This was the most messed up problem I've seen. So then I wanted to see how the car ran. After letting it start, I took out the park wires from cylinder#2 and #4 so it could run on #1 and #2 and the car ran better for some reason. Then we did the same vice versa and it ran the same.

Could someone please help me?? I have no idea what's wrong. Somethings to know is that I think i might have bent a valve because I shifted from 3rd to 2nd going 100, but that should result in no compression in Cylinder#1. Some other things to know is that the spark plugs are all gapped, the spark plug in Cylinder #2 had oil on it once I pulled it out, I have a CEL showing Code 9 which is CPS (I already cleaned the dizzy, so don't know what that's about). Besides that I can't figure out what's wrong and this is buggin the **** out of me. The car runs fine at WOT but at partial throttle the car putters and doesn't run great.

My setup:-

Turbonetics T3/T40E Stage III 57 trim
Custom DIY Ramhorn Manifold
Drag 4 IC piping
JRC 6" IC
Tial 38mm Wastegate
Blitz DD Blow Off Valve
Custom 2.5" piping for downpipe w/ Magnaflow Carsound Cat
Walbro 255 Fuel Pump
OBD2B-> OBD1 conversion Harness
DSM 450cc Blut Top Injectors
P06 chipped with Uberdata with a tuned boosted map at 11psi

 

bad burn/chip?

 

all the injectors have constant power they are opened with ground. Check the resistance across the 2 terminals on each injector with an ohm meter. are the all clicking? jsut because they get power and ground pulses doesnt mena they will respongd to it

 

is the motor smoking? how much vac are you seeing on the gauge? if it has a vac leak the map sensor will be telling the ecu to interpolate between the wrong part of the map

 

O yeah also my idle vacuum is at -10psi which is really messed up cause it used to be at -15psi when i got it tuned

 

did you look for a leak? the map sensor will think its under load when its not and give it to much fuel.... the tune also affects the vacc it will pull at idle

 

There was a vacuum leak but that was fixed before doing all this. Also I think there is something messed up with my EGR. Is there a way I can take EGR because I have an OBD1 ECU. Also I am using an OBDII Dizzy, so would that make a difference??

agreed - definitely still could be a bad injector.

you can try the above test or just try swapping injector 1 and 2 and see if the problem follows the injector or stays with cylinder 1

 

change your plug wires, happened to two cars we've dealt with. try to get a hold of another dizzy.

man your thing reads -10 and b4 it was -15 at idle...

mine reads -21 or so
