Checking the injectors I noticed 2 of them had cracks on the plunger housing.. Not sure if this would have any effect
this is a tough one.I know this is an older strand, but I am at a loss. Looking for any ideas/help/suggestions because right now it's unusable.
We acquired a 96 integra LS non-vtec in May for my son. It had the top half of the engine replaced including intake manifold. Ran perfect all summer long... in September, there was a leak from the water pump and took it in, had timing belt and water pump replaced. about 3 weeks later, the CEL came on. We did some basic things... spark plugs, wires... car seemed better. About 3 days later - light back on - ran to autozone...codes p0300, 0301, 03?? (random misfires) ... took to shop... diagnosed as 2 bad injectors. Both replaced, also all belts. Ran like a raped ape for about 9 days... CEL again! Ran to autozone - misfire 3 and 4 - random misfires. Replaced injectors 3 and 4. ... replaced fuel pump and filter... ran 2 days - CEL again... replaced TPS, Rotor, cap, fuel pressure regulator, gutted cat. Replaced the crankshaft position sensor today...
It never ran the same again or since. I can hear the pump. It's fine. Put straight gas in - no ethanol. Here's what it's doing... no steady idle, bounces between 200 and 1200... once (if you can get it there) you get it above 2000 - runs beautifully. Soon as throttle is released, drops down and tries to "recover" - sometimes it does, sometimes it dies. Can not engage clutch, acting like no gas. needs to be revved to 3k to engage. But, doesn't go anywhere... can't even use reverse out of driveway. After the CKPS, it is able to idle "better" but still drops, usually recovers. In the past 10 days - it's been used 2 - 25 miles used a 1/2 tank of gas. After it has been out "tried to engage clutch" throws misfire codes.. today is 1 and 3 with random. It's like it's in limp mode. The battery is completely disconnected tonight in a thought to completely drain the memory of the computer and try again tomorrow. If the engine is under load, it stalls. HELP!
If I ever get a CEL (check engine light), I always get the trouble code FIRST before I begin "fixing" things.I know this is an older strand, but I am at a loss. Looking for any ideas/help/suggestions because right now it's unusable.

The MAP (manifold absolute pressure) sensor, mounted on the firewall, is what controls the idle, in what is also called a "closed loop". As soon as you stomp on the gas, the O2 sensor takes over, as a "open loop". If it won't idle, with huge swings in RPM, tells me you have a vacuum leak. But you might also wanna check the MAP sensor as well. If you replace the MAP sensor, make real sure you get the right one, cause they're not all the same.Ran to autozone - misfire 3 and 4 - random misfires.

That's how ALL Integras operate. You've got to give it a lot of gas and about half clutch to get it going. Then, once it's moving, you can drive it normal in the other gears. Using reverse takes a bit of practice as you gotta give it a lot of gas too.Can not engage clutch, acting like no gas. needs to be revved to 3k to engage.

Did clearing/resetting the ECU work?After the CKPS, it is able to idle "better" but still drops, usually recovers. In the past 10 days - it's been used 2 - 25 miles used a 1/2 tank of gas.
