Injection Signal
1987 Toyota 4 Runner quesiton.?
I own a 1987 Toyota 4 Runner with a fresh 22RE motor with manual transmission. Lately the truck has been acting up.
When I hit 60 or 70 MPH the truck will suddenly lose all power for in instant and come back. The "check engine" light flashes as it does this.
It is not a clogged fuel filter. I believe it is in the electronics. The lights on my radio also flash off and on when the truck loses the power and sometimes when I put on the turn signal it will lose power too. I have a hunch this has to do with the electronic fuel injection.
I am afraid the truck will just shut down on the freeway because of this. I am kind of a novice with mechanics so if anyone has any advice, I will welcome it. Thanks.
PS Other than this problem I love my 4 Runner. It has almost 200,000 miles on it.
Okay, so if you are positive it's not the fuel filter then I know of two ther possibilities. First off, I had a vehicle that did the same thing, lost power on the freeway and the check engine light would come on. It turned out to be my battery was slowly going bad....three weeks later it died completely and I replaced the battery...ran like new.
On another Toy I had I had the 22r and the fuel pump was going out on it. It would shut down and start back up and that would prevent the fuel from flowing temporarily. The other solution is what you stated it wasn't a clogged fuel filter.
Also, if your voltage regulator, alternator or battery are bad it won't complete a circuit and will cause the engine to lose power. These are some possibilities...good luck!
