Hi guys I really need some help. my 91 civic 1.5 is being a really big pain. so heres the problem. about a month ago the car started idiling real rough, kinda sounded like a WRX when you started it up. i read the code from the ecu and got code 16 which is the fuel injector code. so last sunday i went out to the junkyar and bought 2 fuel injectors and a main relay. helped but still runs rough. the next thing im thinking is fuel pressure regulator.

any ideas thanks

 

Did the replacement parts clear CEL code 16?

 

yea the code cleared. i also am thinking that i might have a blown head gasket. the car has 168xxx miles and im trying to keep it running long enough to get the money fora possible swap.

 

What's the engine?

Why do you think the head/head gasket is blown?

 

its a D15b2 its just another thing on my check list. also the number 2nd sparkpug from the left gets fouled very easily.

 

You may want to start with a basic tune up (OEM plugs, wires, distributor cap, and rotor).

Any smoke from the exhaust? Are you losing oil and coolant? Is the engine overheating?

 

I have recently done the tune up. back in june i replaced the distributor, plugs, wires, alternator, valve cover gasket, adjusted the valves. there is blue smoke comming out of the exhaust and it uses about a quart of oil a week. engine does not overheat. and does not use any coolant.

 

Compression and leak down tests may be in order to determine whether the oil burning in cylinder 2 is caused by a bad valve seal, piston ring, or head gasket. I guess bad cylinder 2 may be the root cause of the rough running engine.

Compression test - see forum DIY section (by Forty04).

Leak down test - http://www.geocities.com/dsmgrrrl/FAQs/leakdown.htm

 

That was another thing on my list to do. if that doesnt work out i will be out of ideas.
