i recently bought an 87 camaro. its got a 2.8 v6 and its a stick. i bought it for 500 and it didnt run. i was trying to figure out why and when i was observing the distributer i noticed it turned. so i immediatly thought it was timing. i got it running every now and then and i tried to time it. it wouldnt stay in time. it would always go like 5 degrees more then what i set it to. i came to find out that the calpak was removed in the ecu. i went to a junkyard and i got a new brain and threw it in. it started up and sounded ok. it popped when i was accelerating. so i tried fine tuning the timing to get it better and nothing happend. i moved chips around onto the old remanufactured brain and the car didnt start. so i swapped it back to the junkyard one and the car still didnt start. i eventually got it running but the check engine light stays on and it says something with the throttle position sensor. but i also saw that it may also be the ecu. anywho. the car now starts then dies. and when it runs, when i press the gas the engine boggs down and almost dies and pops and pings but when i let go of the gas the rpms jolt up again. when the car was running it would stay at 2500 rpm's. idk whats goin on with this car but i also found under the hood there is a black and pink(?) could be faded white wire thats spliced and also the pink wire thats connected to the ignition coil is severed. i cant find the other half of the wire. so for the hell of it i connected those two wires. the blk/pink wire is right near the pink ignition coil wire and it runs into a big wrap of wires.. can anyone help me sort this damn thing out? il take pictures and show if anyone can tell me just how i can upload them lol. i dont know how to do anything on this site..

 

maybe a worn/stretched timing chain set. you can pull the dist. cap then turn the crank back and forth and see if the rotor follows.

 

the rotor rotates. i found that out because i had to turn the crankshaft and see where the rotor was to see if it was on compression or exhaust stroke.

 

im saying rotate back and forth to check for slop in the chain.

 

the rotor? it rotates back and fourth only like a couple centimeters
