Is there anyone in the El Paso TX area that has a spare working stock style MAF Sensor for 86/87 TR's that i could try to see if for sure the one on my car is flaking out?
Been troubleshooting an issue the last few days and based on someone else that was having a similar issue i am, thinking it's the MAF sensor causing the problem i am having also.
I've verified fuel pressure to be correct, stable & rises properly. I have checked over all grounds, made sure connections & vac lines all were good, pulled the spark plugs out to examine them and they all look good. I've done cold and warmed up testing the ohm's on the coil pack pairs with that checking out.
Part of why i am suspecting the MAF sensor is having problems is that when i unhooked the plug from the sensor the idle is smoother and clears up. The O2's are reading more properly with it unplugged than with it plugged in at idle fully warmed up also. With it plugged in the O2's would after she was fully warmed up drop to in the 200's MV and mostly sit in that range at idle, occasionally for just a second jumping up to over 500 MV before going back to the 200's for a bit. With it unplugged the O2's were reading a more normal range at idle like prior to the issue happening and she idled way better also. As soon as i plug the MAF back in she goes back to idling alittle rough again and the O2's go back to being low at idle.
I can't pick up a MAF sensor from any parts place until at least tomorrow and i unfortunetly don't have a spare to try to further attempt to resolve the problem.
She starts fine with only having to turn the key once or twice at most on first startup of the day and doesn't stall, isn't overheating, the SES light comes on with the key on engine off like it is suppose to, no codes being thrown or flashing SES light happening to indicate an issue, no spark retard occuring at any point on scanmaster. If i unplug the MAF sensor, i do see a code 34 show up and it does make the SES come on until i plug it back in then the light goes back out which is normal. I've even reset the computer and made sure the chips were seated properly, with no change.
Bites not having spares of stuff and only having her for a vehicle. I already asked gnEric if he had any spares and all he had were the hot air style MAFs sitting around and they won't work with our Intercooled beasts. Gladly will give some gas money to whoever to come over here and if they want a beer or 2 would gladly buy them that as well.
