SLUGGISH START UP / CHOKING

1992 Honda Accord • 407,800 miles

When I start up my car either early morning or after car has enough time to cool down, the enging seems to be choking (feels like too much fuel) for about approx. 10-15 seconds, very low idle like it's want sto shut off. Then after that priod idles to normal and functions like normal. I had resently replaced the intake manifold gasket because the coolant passage portion of the filter keeps blowing out. Replaced the throttle body base gasket but did not resolve issue. Checked fuel and air lines to throttle body by spraying TB cleaner over but no leaks. Cannot find what could be casuing issue. Could it be the intake gasket again, but not loosing any coolant. Puzzled.

I will have to check the ground + I had installed a new T. Stat. Wondering, is it possible to install the the headgasket incorrectly?

No, it is not possible. If it is installed incorrectly, you would have leakages and oil would not be getting to the head.

Ok I gone through the system and there are no leaks. Checked to see if coolant was traveling through the t. Stat (and it is now that iit seems the hose is now warming up. Did notice that when I step on the gas, is see small amounts of small smoke (like at start up) when the gas is let off. Would it be possible that the since I had the head plained that this could be the problem? I can't even explain it. Also my fans don't kick in. I did a jump test on the rear temp sensor plug and it kicks (in but not when plugged), does nothing on the mid temp sensor. Not sure if because not reached temperature to kick on. Also noticed when car ran for about 5 min. And no fans and gauge few click below white hot line that the heater in the car was not even hot (even thought I installed a new heater core).

UPDATE: Found the temperature issue. A plug was torn off and I wired it back wrong. Fans still only work when jumped (the ECT Switch B : runs fans when ignition if off, and I think the rear TW sensor : runs fans when key is turned to the on position). Fans will not kick in when temperature rises on temperature. Now all of a sudden I got a code 6 on the ECU. Does this mean the rear TW switch went out? Also when I run the car and manually run the fans, the temp still remains high.

5 minutes is too short a time for the heater to work correctly. The fan would only come on after more than 20 minutes of running time.

Code 6 is a fault with the ECT, the one next to the temperature sending unit, just below the distributor. Check the wiring and connector, hope you have not reversedly install the front fan switch and the ECT. That can result in the fans running with ignition off.

We'll, ran the car about 20 min and no fans. Had replaced 3 sensors (on thermostat housing, on head and the temp sending unit & thermostat). No more code 6 but car is still overheating. No Leaks & loosing any fluids. No water in the oil. 1 sensor left but that is for the condensor (i did not chnage that because my a/c is not working right now). Radiator hose from front of housing to upper radiator is very very hot and the hose from T.S. Bell housing to bottom of radiator is not so hot(warm). I will have to check that T. Stat(even thought it's new) to see waht it does but I am now stumpped. Tested fan plugs(t. Stat housing) and both fans engage when key is turned to on, the fron plug by the front upper hose to housing 1 fan engages when key is at off position.

Yup, seems the thermostat is not functioning correctly. Others seems to be working correctly from the test you have performed.

AC does not control the fans when the temperature heats up.

I will try to put on my other thermostat. I had tested that one and it does open when boiled in water like it should. But with that one, I had similar issues, but will try it anyways. Thank you and I will let you know how it goes.

Ok, so I changed the thermostat and same problem, no change. But I do notice that (example: when the fan kicks in, the engine kind of drags a little-power draw), it sounds like it's doing that but no fans. I opened the rad cap and does no seem like there is any flow, from what I can tell. I see no fluid from weep holes on water pump (no fluid loss) and can't seem to hear any whining from there either, but could not mean that the water pump went out. While car running, I manually kicked the fans on to see if the car would cool down and nothing, remained high. There is pressure on both hoses but only hot on upper(front rad hose). Heck i've just about changed everything else with no results (that has to do with the cooling) and just wonder if it just might be the water pump. It's only about a year old but do put quite a but of miles on her daily(110 daily).

I believe you are not experiencing overheating but rather the gauge is not accurate. Did you check the ground circuit connections, especially the ones behind the headlights, attached to inner wheelhouse panel?

When fans kick in, does it stop running after a short while?
