sounds like you have air in your engine coolant. you should have a bleeder valve somewhere near the thermostat housing metric size 12 nut , with engine off and cool remove radiator cap and loosen bleeder bolt add coolant to radiator until solid stream of coolant comes out bleeder then tighten bolt repeat if necessary, until all air is removed. hope this helps
that might be it but from my experience with hondas and especially preludes it is either the IAC valve located on the front of the intake manifold or the FIT valve located on the bottom of the throttle bodie. if you unplug the IAC it should be a very fast idol up and down that means that's not ur problem. if that's not it next check the FIT. there will be 2 coolant lines running to the valve and 2 10mm bolts holding it on. pull the FIt off and there will be 2 8mm bolts on the end will also have a Philips head. use the *mm to take the plate of and there will be a big white ring with a silver dome shaped piece of metal in the middle take a big screw driver and stick it in the slot on the white ring, and tighten the ring back down. over time these things come loose and will cause idol surge. preludes are nitorious for it.
How can I check the ENGINE COOLANT TEMPERATURE (ECT) sensor on my 1991 HONDA PRELUDE SI 2.1L
underneath the cup holder
Check oil level. Check that the engine is warm enough (maybe blown thermostat). If not then you should have a check engine light. Short the service connector and count blinks and figure out what's wrong. Do necessary repairs.
When a check engine light appears on a 1992 Honda Prelude dashboard it means the ECU is get an abnormal reading on one of the automobiles functions. Use a diagnostic tool to flash the ECU and find the problems associated the car. The flash will also turn off the check engine light.
Considering there were five generations of the Honda Prelude, this question needs to be more specific. The Prelude lineup featured a variety of engines over the years of different engine families, ranging from 1.8L to 2.3L The fifth generation Prelude (1997-2001) featured a 2.2L DOHC VTEC engine rated for appr. 195-200bhp. The fourth generation Prelude (1992-1996) featured two different engine families, the "H" engine and the "F" engine. The "H" engine in the 4th gen is a DOHC design, the 2.2L variant having VTEC, featured in the VTEC trim and being rated for 180bhp-190bhp at the end of the generation. The 2.3L "H" engine was DOHC but did not feature VTEC, was found in the SI trim, and rated for 160bhp. Finally, the basic level trim featured the 2.2L SOHC "F" engine, which also did not include VTEC. The "F" engine in the 4th gen Prelude is rated for 125hp. If you want more information on the older Prelude, or Prelude engine options outside of the USDM, check wikipedia as the Prelude article is maintained by dedicated Prelude enthusiasts.
Probably a vacuum leak. Do you have a code P0171 or P0174?
low break fluid?
That is very possible but most likely yes
Run a compression check and see if you have a dead cylinder. you should check you timing Check the firing order.
If you are replacing a H22 engine with a later H22 variant it can be done but requires other items to be replaced. Research research research, check the car forums.
you should check your engine...like now...
Check your owners manual. There should be a description/picture of the check engine light.
Could be many reasons. If there is an check engine light, have the code pulled with a ODB2 scanner from any local garage. Reference that code with what it means and you have a better idea where to look to solve the problem.
Check your engine. Check your fluid levels and add if needed.
roumoured this fault is a recall? investigate
jump terminal on the driver side with the blue-green wire and the brown wire then start engine and using the light gun check for tdc at a tolerance of 15 degrees
if ticking noise is in engine, u most likely have a worn hydraulic lifter. check oil for correct volume and viscocity
Yes, but it will involve modification to the body of the car. Check Prelude forums, the modification has been done and documented in detail.
check engine light. it means you should eather check your "codes" or go to an auto shop and tell them your check engine light is on. sometimes its free.
You should check the battery,transmission, and maybe the engine
The light should stay on whenever the key is on and the engine is off.
Use an OBD code scanner to find out why the computer has turned on the check engine light.
check coolent level
check your egr valve or throttle positioning sensor
