I have a 1985 4-Runner that has a 1990 7 MGTE swapped into it. I've been reading over this forum quite a bit and have replaced the spark plugs and tried to set the timing.
When I put in a jumper wire where it says it does nothing for where the timing mark is. So I set it to 10 BTC anyway and it now runs like poop and falls on it's face when you try to give it gas and get into boost. In fact the motor makes a kind of BLAAAAHHHHH sound. I think I just retarded the crap out of the timing.
Any ideas on why the jumper didn't do anything for me?
Should I just replace the TPS? I read that it may go bad and I have no idea how many miles are on this thing.
Also worth noting is that the previous owner didn't hook up the check engine light when they did the swap. So I have no idea how to check for codes.
It also idles at 450rpm when it's cold and 900rpm when it warms up. Even when warm it will almost die if you stab the gas and rev it up. When the rpms come back down it goes real low(like 200rpm) then comes back up to 900 rpm.
Another thing is that it isn't snappy when you press the gas in idle. It has a slight hesitation to it. It also feels like it may be missing a little on acceleration under boost.
I just got this truck a week ago and I am trying to learn how to fix it myself as I don't want to pay a mechanic what I should be able to learn and do myself.
