Screwed up CRX

[tylonalsnifnfool]

For some reason my 88' CRX Dx is soooooo unbelieveabley slow it's pitiful. it acelorates from 0-60 in about 45 seconds and i have no clue why. I have checked all the obviuos like spark, the plugs, oil change, intake, and all seem to be fine. I put a cold air intake and a "high flow" cat on but it didn't seem to do a single thing. Any sugestions would be greatly apriciated.

it feals weird when i drive it like i'm towing somthing and it also stops acelorating at 75-80mph. it feals like the motor is pushing hard but somthing is holding it down. Also I have no top end in 3rd and 4th gear. As soon as i hit 4000 rpm's it just kinda stops.

When was the last time the fuel filter was changed?

 

[tylonalsnifnfool]

ah yes the fuel filter....................just changed it about 2,000 miles ago and i have had the problem for about 10,000.

 

[rudeludenotmeanthough]

uhh.. take off the E-brake when you drive!!1

 

[tylonalsnifnfool]

nobody knows? or has had this problem?

 

[zaneithan]

maybe you blew a cylinder

 

[tylonalsnifnfool]

how can i check if a cylander is blown?

 

[mdlax1]

compression check..

im sure your "high flow cat" isn't helping either

Check your ECU for a flashing red LED. If you have a failed sensor, your ECU may be running on the backup fuel and ignition programming (limp home mode). The backup programming has limited fuel and ignition, and generally has around a 3800 rpm revlimit. There are a couple of sensor failures that don't illuminate the CEL, and there is a possibility your CEL is bad, so you won't get an indication of a problem. If everything with the ECU is fine, check the fuel pressure. How many miles are on the car?

 

[tylonalsnifnfool]

it has 190,000 miles on it and i don't think it was very well maintained before i got it. i'm trying to keep it alive as long as possible cause i like to use it as a fun little winter car.

ya i had the same problem it was a bad injector and cloged intake when i bought the car

 

[uglycamocivic]

i had the same type of problem (before the swap) I took out injectors and cleaned them and then i found out the tdc sensor was bad in the dist. So i had to get a new one ..................


Try that stuff.

 

[cxjon]

do a dpi two a mpfi swap

 

[tylonalsnifnfool]

to do a multiport can i just strap it on or do i gotta re-wire it?

check the ground wires to the ECU. there was a problem with some civics having bad ECU ground wires/connections. i read about it on some honda service bulletin thing. worth checking out.

also, you might just need a new ECU (no MPFI swap).
