Sorry put flag for review on the answer.I thought that was the way to add more info to the answer for additional feedback.
I should correct my definition of the problem . When cruzing at a lower RPM s 1000-2200 when I first give it a little gas it bogs down and will continue to bog down until I give the car a little more gas. Once I give the car more gas it is fine. It also idles a little rough and seems to ping to my ear but mechanic says that is a normal pinging sound. I have decent power and get 31mpg. It will rev up to 4 grand fairly easy. It is just a pain giving it more gas each time it only needs a little as I end up speeding up then down, up then down.
Also could this be a related problem and if not what is a possible solution? I had to disconnect the air control valve on the air filter cover because it would close and stay closed (it is usually open when not running) thus only bringing in heated air from the exhaust manifold. The tube that went from the air control valve was getting vacuum, it went to a small round disk closer to the TBI on the air filter cover. That disk has two vacuum inlets, one for the air control valve and one that runs to the canister purge valve solenoid. What can fix this air control valve so it opens when the car warms up?
So Far I have replaced and checked the following
Coil, Plugs, Cap Rotor. Plugs are champion rec. By dealer.
Timing done by garage.
Knock Sensor (there is none)
Air Change Temp Sensor
Idle Air Control Valve
Gasket under Throttle Body
Throttle Position Sensor
Computer was replaced a few years ago
Checked EGR Valve
Checked for vacuumed leaks several times
Cleaned Throttle Body
Fuel is super with some Lucas Fuel additive
? Could it be the
1. Distributor Pick up Plate?
2. Could it be the EGR valve, I had someone else check it? Could it be the timing, I did change a lot of sensors since it was done but the problem still existed before and after?
3. That air control value issue, though it ran the same when it was open or closed.
Anything else ?
Thanks for the help
