Setting timing on my 87 2.9 4x4 Ranger
I would like to know about setting the timing on my ranger, I know it is to be set at 10 degrees BTDC, but it dos'nt seem to have a electronic timing advance or vaccum advance that I can find. I just bought this Ranger and it seems to have poor performance and poor gas millage (14 MPG on the highway as checked this last weekend) I have replaced the plugs, wires, rotor, rotor cap already. I did run it this last week end at TDC so that is part of the problem I am sure. It has electronic fuel injection so I think it did some auto adjusting for the 10 degrees the timing was off by. my haynes manual speaks of a crankshaft timing sensor that I can not find near the timing marks on the shaft (manual said it is on the v6 models) I have not been able to locate the electrical plug that plugs into the sensor either. (Now the guy that I bought this from said that the engine had been rebuilt a couple of years ago, I wounder if they never reinstalled the timing sensor or if this v6 never had one. Does anyone know if all 2.9 L had a timing sensor. If they do require one than that is most likely my problem on gas millage and performance. I also have a leak at crossover pipe and the first cat. It would seem maybe the cats are plugged. I had a 1986 Ranger 2.9 L 4x4 a few years back and it always ran great with much better performance and gas millage. Any ideas hear. I noted after reading a few things in this forum that their is talk of a timing plug, is that the sensor or something else completely? I also have pacesetter headers that I had purchased for a 1986 Ranger I have since sold, does anyone know if they will fit my 1987 Ranger, and were can I get some hints on installing them without breaking off the header bolts? Since the motor was rebuilt a couple of years ago it would appear that the rust on the bolt heads are at a minimum and that a little added heat to the stock exhaust manifolds and heads may make the job a bit easier? What type of penitrating oil would you use to get the job done? I would appreciate any help you might offer, thanks again.
