Ok here is the senerio I was driving my car and I was pulling right out of second gear and going into third and my engine felt like it hit a revlimiter or something not saying that it did but it felt like that. Instantly the cars check engine like came on and and I pulled into my friends drive way the car went to 1500 rpm and stayed there which is not normal and my car was blowing black smoke out of the exaust. After observing the smoke and idle I concluded that it is not coolant getting past the gasket, I turned the car off and turned over agian everything went back to normal check engine light went off and car idle fine. I drove back to my apartment on the way didnt rev past 3500 parked checked oil made sure it was toped off and all other flued check fuel pr reg fine and everthing was normal. I went to start the car take it around the block hit about 5000rpm and same thing happened all over agian check engine light and black smoke restarted the car everything back to normal.. Please help

 

maybe you are low on oil or something else. as soon as the comp. sees that a check engine light is on it will put the car in safe mode that is why you hit the rev limiter. not sure what your problem is.

 

You really need to find out what code the ECU is throwing. From there you can figure out what your problem. If you have a service manual, look up the procedure for pulling the ecu codes. I'm not sure what would cause that, besides a mis-fire, or severe detonation. What engine/car do you have?? What fuel octane are you running? Have you made any changes? We need a little more info, to help you better.

 

reset the ecu and if the check engine light pops up again look it up.

 

ok b18c1 skunk2 mani jun cams cam gears lifters springs 93 octane pump gas msd ignition aem fuel rail dc headers apex exaust jun chipped p28 ecu. the check engine light comes on when I hit about 5000 rpm and then throughs the light. I can stop the car turn it off and then back on and the car runs fine no check engine light as long as I keep it at a low rpm and I have my oil toped off. however when it happened the first time the oil was low. maybe a quart or two was in there.

 

from what i just learned keep oil in her!!!

bump for my dead b18

 

i know I did a full oil change maybe 2000 miles ago and I do a new one every 2500 miles
