EricsGSR

Ok, bought the car about 2 months ago. It's a 95 GSR with about 130k on it. The car has always (since I bought it) given me an issue when at low rpm's it will kind of miss or hiccup. Like if I cruise through a stop sign in second gear at like 1k rpm's. Then the past two days it started acting really weird.
The car doesn't want to rev (in gear) up and accellerate as it normally should. It feels like it's just being held back a LOT. It isn't missing or anything, just feels like the timing has been pulled or something and it's in limp mode...i don't know.

No CEL's...I checked for any stored as well.

Recently replaced, plugs, cap, rotor, wires, and fuel filter. Checked timing as well and it's spot on 16.

Anyone have any ideas? Maybe TPS, CPS, or some other sensor? I have no CEL's so I'm having a hard time thinking it's a sensor.

Distributor maybe? Is there a way to check the dizzy to see if it's working properly?

Thanks in advance guys.


PROBLEM SOLVED! Was WAY out of time. 10 degrees (roughly) instead of 16

try a compression and leak down test

also it runs good till its fully warm.

cat?

EricsGSR

Cat is brand new as of a month ago...this just started 2 days ago

This is completely normal, nothing to worry about second gear at 1000 rpm is too low to produce any power. Thats why it bogs. The more gas at the lower rpm like that will cause it to bog more. Try axcelerating very slowly it will yield better results.

I understand that, this is my 12th honda. It will bog and hesitate throughout the entire rpm range. It feels like a bad cap and rotor would feel. Like its pulling timing. I'm going to check fuel pressure this weekend and try to rule that out.

Fuel pump primes nice and loud, checked all sensor connections, checked for vac leaks...I'm stumped...

EricsGSR

I floor it and it basically goes nowhere when this happens...and apparently it's an intermittent problem because half way home from work it ran perfectly...I'm sure it'll do it again...ugh!

I have a very similar problem... I've been searching for answers for over three years that I've owned the car. Started threads, replaced MANY parts, and rebuilt the engine to no avail.

Good luck to you sir

idk how are your grounds? FPR? maybe test your injectors? o2?

EricsGSR

Ugh...not what I wanted to hear lol. Any other ideas?

EricsGSR

How can I test the fuel pressure regulator?

fcm

I would do a compression test.
I would check the TPS.
As mentioned, check fuel pressure.

How did you check for vacuum leaks?94

EricsGSR

The old carb cleaner sprayed on all vac lines.

How can I check the TPS? Multimeter?

01oemTeggy

Oh you didn't mention that part. That is most defs weird.

steveo135

This is kinda my next guess for me.. something fuel related

you need a fuel pressure gauge, but im not sure where you tap onto the system to get the reading

kchungb17a

What kind of plugs and wires did you use? Is the distributor OEM?

stowne78

the TPS is just a potentiohmeter (pot, or variable resistor), take a meter and measure the resistance as you move the lever. If problem is intermittent then do it several times, the resistance change reading should be nice and smooth, if it is jumpy then replace it.

worx

we had a simillar issue with a gsr of ours and we ended up switching the dizzy it fixed it

EricsGSR

NGK blue wires and NGK plugs as well...both new and gapped correctly. OEM distributor as well.

EricsGSR

Thanks steveO! I'm leaning towards fuel...hoping it is just some bad gas.

Anyone know the part interchangeability for a 95 gsr dizzy? Will any OBD1 Vtec dizzy work?

any obd1 vtec dizzy should work. I am not sure but maybe auto zone can test the coil or some thing.

Butain works better, I just use a Bic lighter, or my Benzomatic torch, turn it on, [without lighting it, da].94
