'86 Camry, manual, 233K
I'm having a problem when coming off of idle/letting out the clutch to take off where the engine stumbles very badly. If I don't depress the clutch several times and give it gas while getting the car up to speed, the engine may die. The stumbling causes front end to shake pretty badly until the car is crusing.
The engine doesn't noticeably hesitate or miss once up to speed. In fact, the car drives and accelerates best when on the freeway. The engine will rev without missing or doing anything unusual at a standstill. Also doesn't matter whether it is cold or hot (ambient or engine), though it is much worse when cold.
My brother and I recently checked the timing, pulled the plugs, cap, and wires, all seem acceptable. Cap, rotor, and wires are pretty new. Fuel filter was also replaced with timing belt about 25K ago. We even cleaned the coil of carbon deposits as I have heard this can be a problem with the IIA.
The problem has been getting slowly but progressively worse, perhaps really bad the last 1K or so.
I'm going to have access to my friend's workshop in about a week. Any hints as to where I should look first with this problem?
Any advice greatly appreciated!
