So I had my 97 Acura Integra apart to do my head gasket, and it was the first time ive done a head gasket so I wasn't 100% sure which was to be dis connected. Anyway I disconnected the banjo bolt for the fuel filter to relieve the pressure or whatever it said in the manual, and the regulator vacum hose. I put it all back together, plugged it all in and it runs but doesnt idle and if it does, it would be at 100 RPM's, very very low. And this was not a problem before I took it apart, idled fine around 750. Only way I can keep the car running is too give it gas, and when i let up it nearly dies.
What can be the problem here? As I said this wasn't a problem before it was all apart.
From what I can tell from reading my manual, the fuel pressure is too low and its causing it to barely idle?

Any help / tips, etc would be greatly appriciated..

Thanks,

 

What CELs are you getting? IACV plugged up and is your coolant properly bleed? It's probably not anything to due with fuel pressure but rather something to do with the IACV, TPS/MAP sensors.

If the engine is firing up I would say fuel is *ok*. The super low idle is most likely a result of a idle air control valve (IAC) problem (or some sort of air delivery).

If I was trouble shooting this motor I would:
1. Check compression to ensure head gasket is sealing (super low compression can cause this too)
2. Make sure intake manifold, throttle body, and IAC are installed correctly
3. Last, I would use a gauge to check fuel pressure

 

So heres what ive come to.
It idles at 1000 or so, for like 2 or 3 seconds after i rev it to 2 - 3000rpm, and then itll drop right down to like 300 - 400rpm. I think I have a vacum leak because when you hammer on the accelerator from the low, low RPMs theres a big delay until it finally revs, sounds like bog almost.
Heres what im thinking, every bolt on the top of the intake manifold are in, tightly. However I didn't have a stand / hoist so I didn't bother crawling underneith and putting the few nuts on from underneith the car on the bottom of manifold ( New intake manifold gasket ) I think that could possibly be it? Not too sure though,

 

Sorry what exactly are "CEL"\s. amd IACV? I didn't bleed the coolant no, i just poured it in. Don't have too much mechanical knowledge with these cars, but I did manage to do the head gasket without much difficulty.

 

CEL is Check Engine Light and IACV is the Idle Air Control Valve. Pretty much check all the sensors and vacuum hoses on the intake manifold. Are you sure you reset the timing right and had everything at top dead center? Have you checked it with a timing light?

 

Couldnt get my hands on a timing light, but yea my CEL is on and I tried pulling the 7.5 amp fuse out for 10 seconds, no luck. Ill try for a minute or so again shortly here. Should the car be running while I pull it out? How do I bleed my coolant, or where is my bleed screw ? Cant seem to find out where in my manual, also everything seems fine on the intake manifold just the 4 nuts or so that you go under the car to install em, arnt in yet. Would that possibly be it? Or my coolant not being bled ? Im thinking either of those

 

No the car shouldn't be able to start when you pull the fuse. To bleed your coolant there should be a little nipple like you have to bleed your brakes. It is usually on the bottom hose where it goes into the motor. Also YES those 4 bolts are causing a huge vacuum leak and could be the cause of all of your issues.

 

Hmm then I have a feeling if I do both, bleed the coolant and put those nuts on the intake manifold my problem should be fixxed as it didnt have this issue before I pulled it appart to do the head gasket..

 

Can u give me better details on how to bleed my coolant exactly? Like where is this hose exactly, sorry for so much questions haha all this stuff is just new to me

 

To be honest I don't think you need to bleed your coolant but it never hurts. It has to be those missing screws or your timing might be off by a tooth. Its was always a bitch trying to get the timing back how it use to be.

 

Install the "4 nuts", gasket is probably leaking.

Coolant bleed valve, #10 is on the upper rad hose water outlet, #6... http://www.acuraautomotiveparts.org/...ystemcomp=List All&vinnoT=&trim=&trans=&view=normal 94

 

Perfect, thanks.
