ok so i got the crx about 99% done. for those who done know its a 91 crx si with b18c1 engine running a obd1 p72 ecu. really all she needs is an allignment and an intake tube. so i was driving today, and i was taking a ramp to get from one road to another. half way up the ramp the car starts to stumble. when i get off the ramp the car is running like ****, barely has any power and just dies on me. i try to start it up, and it starts but barely, and its running like **** and doesnt want to hold idle. it runs really rough. i shut it off and start to look around in the engine bay looking for anything out of place or broken or leaking.

car isnt leaking a drop of oil/coolant or anything else and there is no CEL. i had just replaced the timing belt, water pump, and crank pulley. spark plugs, wires, coil, cap, rotor are all brand new. one thing to note is that im running with no intake tube. so after i get done checking everything and figeting with the electrical connections i open the throttle body. i see smoke but only a little bt and it goes away almost immediately. smoke was a grey color. after letting it sit for like 20 minutes, i go to start it and it starts back up again a little rough at first but smooths out. i rev it up a little and everything seems fine. i try to limp home, and about a mile down the road the same thing happens. it died on me and would barely start back up. so i called a tow truck and had it towed home.

heres some vids of me trying to start it and getting it started. im sorry for the quality and darkness but it was 11:30 pm and i was stranded on the side of the road.
vid one
vid two
*the rattling sound in the second vid is the change in my ashtray rattling*

what could this be? blown headgasket? could i have sucked something into the engine due to the lack of an intake tube? i was a clear night and i didnt run over any rocks or dusty patch or anything.

keep in mind that this was a sudden thing that happened without warning. car was running perfectly then just stareted to run like **** and died on me.

im draining the oil tomorrow to see if theres any coolant in the oil or anything else that could be bad.

any and all help is greatly appreciated.

that sux! Almost sounds like a VW engine running like that. I want to knowas well as I am looking to get a B18C or the B16A1. Let us know what you find. Hope it isn't expensive!

new information... timing is DEAD on and ignition rotor is in place and solid, as is its screw.

compression test results... 225 210 210 215

no coolant in the oil but the coolant was unusually low. i changed the oil and topped off the coolant and the car started up with a little hesitation. idle was a little surge-ish but smoothed out and ran fine. what the hell is goin on?

so is the car runnig fine now, would hate for that to happen to me.

GSRCRXsi

i guess its running fine, im kinda afraid to drive it. i dont wanna break down again or hurt something more if driving it would hurt it.

if there is no CEL. I'd check for a vacuum leak.

one, theres no vaccuum leaks, i checked. and two, this problem would not be caused by a vaccuum leak. all a vacuum leak would cause is a surging idle. and thats not the case. the car seems to be having an intermittent problem (or only when warmed up) where at some point i seem to be losing massive amounts of fuel or spark and the rpms drop and the car dies on me. if i do get it running when the problem occurs, it runs horribly bad.

Check your fuel pressure, also check your your injectors (when I say check the injectors, i mean make sure they arent cracked, and check the injector pulse with a noid light.). You might have flooded the engine, and when you let it sit it had time to go back to norm. The smoke you see in the throttle body should be vaporized fuel or crankcase ventilation from the head, nothing to worry about.

When its running and hesitating, are there any funny smells, like out of the exhaust or anything? Is there a sweet, coolant burning smell, or a rich smell.

Also check your throttle body, the tps might cause invalid throttle response and injector signal problems due to wrong throttle position.

Cant really think of anything else without more info...

Check all your wire connections. And check your grounds too I guess. A bad sensor could also be your problem. Make sure the eacv sensor is hooked up on the intake mani.

mine was cutting in/out, ended up being breaking down spark plug and bad plug wire

check those injectors. If you have to get a long small screw driver and put one end to the injector and listen to the other end. listen for a clicking noise. after that try replacing your plugs because if your flooding the motor you could have fouled the plugs.

Is the ecu stock or is it chipped?

also check your dizzy...

It was probably the low coolant. When you dont have coolant to your IACV it can make the car run pretty messed up. Normally I wouldnt think it would die but mine ran really awful for what you would think was a minor problem.

bump. i got some more vids to help show whats goin on. basically the car runs fine until ive driven it for a little while. the following vids are in chronological order.

first two vids are of me doing some "sprited" driving on a road right by my house.

http://www.mainstreamtopics.com/memb...i/IMGP1101.AVI
http://www.mainstreamtopics.com/memb...i/IMGP1102.AVI

the next few vids are directly right after those runs. i stopped in my driveway and was talking to my dad with the car running and it started to act up again. i grabbed the camera and shot it.

http://www.mainstreamtopics.com/memb...i/IMGP1104.AVI
http://www.mainstreamtopics.com/memb...i/IMGP1105.AVI

now what you see in the first vid is the same thing thats been happening. the first time this happened the car ran A LOT worse. and the car was a lot harder to keep runnning. you can hear the car surging and running uneven. any ideas?

GSRCRXsi

ecu is not chipped.

everything inside the dizzy except the sensors and the ICM, are brand new.

i topped off the fluid in the radiator and it still happened. but not as bad this time

problem seemss to be only when the car has ran for a little while. the video shows that the car was running fine, then it starts to run bad then it gets fine again.

How are you "topping off" the coolant? are you filling it up then running the car and watching the bubbles come out and adding more as needed?

yes

and yes i see my replies, but i dont see it as a fuel problem. the problem only happens sometimes, i think if i had a bad injector or low pressure then the problem would be all the time, not running perfect then all the sudden die. nonetheless, i will get to it, i just havent gotten to it.
