2006 210 fuel in oil

[DW SD]

what happens is the diaphragm in-between vacuum side and fuel side ruptures and you suck fuel in through the vacuum line.

Ok...so with my symptoms of hesitation off idle but running good at WOT make sense with that fuel pressure regulator out?

[93Euro]

Is there more vacuum at idle ?

[DW SD]

probably the fuel pressure is off therefore mixture off. Do you have a fuel pressure meter?

[93Euro]

I'm on my way to go get one now after watching a YouTube video on how to diagnose a bad diaphragm in the fuel pressure regulator

[93Euro]

I put all the injectors and fuel pressure regulator back in the rail but not into the manifold. Nothing is leaking. Actuated each injector again with the 9 volt battery. Everything seems to be working. Maybe an injector was stuck open but worked itself out? Going to put it all back together, run it in the driveway, and see what happens. It was the first time out of the season after sitting since November.

finally got this thing back together this evening (was waiting for a throttle body gasket that tore on disassembly). I'm not sure what it normally sounds like with the plastic cover off. I would imagine i would have noticed this noise before, but maybe not because i wouldn't have been giving throttle while back there. It sounds similar to a free wheeling bike sprocket, maybe has something to do with the noise of the injectors. They seem very loud also. Is this normal? the sounds is just at light throttle, then goes away.

it doesn't sound right. initially, I thought a valve lifter. Did the oil level rise again?

[93Euro]

Oil level still looks good, but I just ran it in the driveway. Last time out when I was having the hesitation issue, it would rev fine when not in gear. Under load is when I had issues. The sound , sounds like it's coming from on top of the motor, not inside. The loud ticking is the injectors.

[DW SD]

In infrared temp gun might be able to pick off an exhaust port less hot than the others. I'm assuming if one injector is stuck, that cylinder would be over rich and you'd find it cold compared to others.

A spark plug would give away an over rich cylinder, too.

You might try a heavy dose of sea foam in the fuel. Some suggest ATF for its detergent properties to clean an injector, too.

Hopefully, the first round of fuel in the oil didn't foul (wear) some of the valve gear, creating noisy valve train. Once the lubrication properties are diluted, all sorts of bad internal things can happen.

You didn't open up the oil filter upon the oil change right to look for shavings? Or see sparkling metal in the oil when you drained it? I sure hope not!

[93Euro]

If an injector was stuck it wouldn't click right? While it was running I stuck a screwdriver to each injector and put it to my ear and I could definitely hear each One clicking. I could pull all the spark plugs again after running in the driveway since they were new I guess I'd have a better idea of what they were doing. I was thinking after I ran a little bit I would change the oil again to to see what it looked like.

[93Euro]

well I finally put in a new set of injectors and a new tcp sensor too. Still not right, but it does seem like its running better. still no fuel in the oil from running n the driveway. It has something to do with the position of the throttle. i can ease on the gas all the way to 3000 rpm and everything sounds fine. If I gas it hard, it stumbles around and hangs about 2000 rpm. then i back off the throttle a bit and it clears itself out and jumps up to around 3000 rpm sounding normal. seems like its getting too much fuel on a hard throttle.

[prowakeskater]

too much or too little.

no codes being thrown?

how old is the fuel

[93Euro]

too rich...I haven't hooked up a scanner to it...Got the fuel at a marina last time out in March. started have problems right after that. This is what the plugs look like after i let it run for while when its running like crap...when its running fine, plugs look normal when i pull them...BTW those are new plugs

[DW SD]

Are those platinum plugs? I had thought those were a no no for old-school distributor type ignitions.
