88subaru

The car is struggling on idle. I’ll look it over

How do you know what code it is, and where and how does it tell me which codes are on it?

Where is the diagnostic port on my 1988 Subaru GL wagon with the ea82? Is it a 9 pin plug, or is it the 16 plug? Any help is appreciated.

Scoobiedubie, when I start the car, it’ll run high rpm then stall. If the O2 sensor is faulty, could it cause it to hesitate when trying to accelerate?

I have a 1988 Subaru gl. There appears to be 3 coolant temperature sensors on here. There is one in the radiator- 2 wires. One on the thermostat housing that is two wires, and one that is a single wire connector with a little spade on it. What do all three of these do separately and which one would control my fuel? Also, what are the ohms supposed to be on all three sensors while unplugged with the engine off? I'm having issues with it running rough. It won't idle but for 2 seconds on start up, then it stalls. If I start it and rev up the throttle, it'll go up to 4,000 rpm, but as soon as I let off the throttle it'll lower rpm quick then die. If I spray starting fluid in the tb, it'll run perfectly all day long. The fuel injector seems to not be spraying the right amount of fuel. What sensors control the fuel injection on an spfi ea82 motor? I have excellent fuel pressure, that's not the issue! I've got a clean throttle body. I have replaced the following- Fuel tank, fuel pump, fuel filter, fuel injector, vacuum and egr solenoids, egr valve, iac valve, spark plugs, fuel pressure regulator, fuel pressure dampers... Any help/input is appreciated.

Thank you Dave. I'll check it out

But it's injecting the fuel properly. It's gotta be a sensor problem

Sea foam through the vacuum lines makes it run great as well

Yes- it'll run off starting fluid all day long

Why would the CTS control the idle/rpm issues it may have?

Naru- I rechecked the fuel pressure. After replacing dampers, I've discovered that it has 23 psi of pressure on the fuel system

Ok. Sounds good.

I have replaced the whole fuel system- pump, filter, tank, tank cap, injector, IAC Valve, TPS (properly adjusted to specs) The car has only 160,000 original miles on it, and yes it has been sitting for 6 years. Hence why I replaced the fuel system. I have not replaced any distributor parts. I have replaced the timing belts and they are correctly timed. The throttle body is completely spotless of dirt and debris. The fuel pressure regulator has been replaced, and is working fantastic. 38 psi of fuel pressure coming from the fuel pump. Clean fresh fuel. I have not replaced the CTS, should I try doing it?

My Subaru has the ea82 SPFI motor in it. The car starts, however once you start it, it'll stall 3 seconds later. I can hit the throttle and it will run continually but runs rough when you try to accelerate. You have to find the sweet spot. Also when I put sea foam through the vacuum system it runs smoothly on idle and acceleration. Another question- there are two solenoid valves on the top of the motor. Are they both egr vacuum solenoid valves, or what are they? I know one of them is the egr solenoid valve, any help is appreciated
