Toyota DX Hesitation

Q. Hello Vince! My has a 1988 Toyota Tercel DX with a 12 valve, 4-cylinder and manual transmission. The car has 145,374 on it. No A/C, and it uses a carburetor. We had the replaced a little over two ago.

I must admit not very mechanically adept, so asking for some advice. Her car to lurch forward at times in second gear, occasionally in There are times it almost when starting to accelerate a stop, but not always. This which has gotten worse time, with periods the problem seems to disappear for a day or It does seem to worsen on days. She’s wondering if her is sticking.

I did replace the spark plugs and was a brief improvement, but it didn’t long. I’m wondering if you may what the problem may be and if its something a would be able to tackle or if I take it to a mechanic? If I should get it to a would you have a rough how much it may cost and the number of it would take. They $60-65/hr.


A. The carburetor on your doesn’t have a choke, the to 1990 Tercel used a venturi carburetor. You’ll very few technicians who have the and expertise to even adjust one of

The 1987 to 1990 Tercels their own very unique problems. The most famous one and the one is a severe lack of power and or hesitation when accelerating.This is by a momentary leaning of the air fuel

What happens basically is the oil control seals on the valve deteriorate and allow oil to drip on the of the intake valves and when the turned off, it heat This heat soak the oil to carbon up on the back of the intake Eventually the carbon build up so bad it actually blocks the air flow the cylinders. This process over a number of months and is so you don’t notice it until one day the car falling on it’s face.

The people best qualified to this are at your local dealer. They have this problem many and know exactly what’s It should take the dealer an hour to confirm my diagnosis. involves removing the spark and actually looking at the backs of the valves with a borescope. worth it to pay the hour diagnostic fee and be what the problem is.

The fix for this is expensive once the is confirmed,you have to decide if the car is it.It involves removing the head and cleaning all the valves and with new valve seals.
