Ill wait a few minutes and itll start.....   2 things are possible, ignition or fuel...just tinkering around havent been able to figure it out ............Ive replaced the plugs.rotor,cap and wires but nothing seems to help.it simply runs rough!! BTW when I pulled the old plugs the elctrodes were eatin away and the plugs looked terrible!! they also had plug extentions on all 3.....I dont know why? the car also eats oil like thiers no tommorrw!! any ideas?? the speedo reads 104K....or so it sez!? the clutch pedal isnt that worn down so it could be right, ...I belive it was not replaced Replies to this message: zaken1 (Aug 21, 2009 11:48 am)

Replying to: drewkohls (Aug 20, 2009 2:16 pm) When the check engine light comes on under the conditions you listed; it almost always is caused by the "insufficient EGR" code. That can be triggered by too lean a fuel mixture, or too much spark advance, or intake or exhaust modifications, or a clogged or disconnected EGR valve; any of which can cause the motor to run at such a small throttle opening that the EGR valve does not receive enough of a vacuum signal; so it does not open as far as it normally would. If the compression is too low; it can also set that code. These engine will not tolerate changes from stock specs.   The code readout is turned on by shorting two terminals in the fuse block under the dashboard; but it's been so long that I forgot where the terminals are. Sorry about that. It's in the service manual. Replies to this message: drewkohls (Aug 23, 2009 4:52 pm)

Replying to: riversidedan (Aug 20, 2009 4:17 pm) It sounds like the reason they put extensions on the plugs was because they were fouling from all the oil the engine was burning. There is no way to tune out the consequences of low compression. So since that is probably the root of the problem here; run a compression check on all 3 cylinders. Stock compression on that motor is 195 psi. If any cylinder is below 170 psi; you'll never be able to make it run right without an overhaul.

Replying to: zaken1 (Aug 21, 2009 11:42 am) I do not have an EGR valve though. Some 89 models didn't have them, when i rebuilt the head because i had a burnt exhaust valve i started to look for why the valve burnt. the first thing i looked to replace was the EGR valve and there was none. so i did some research. I believe the valve burnt because the catalytic converter was improperly installed by the previous owner. I believe the timing is supposed to be 6 degrees or something like that. I cant remember for sure but i can check within the week, do you remember what the timing specs are? also, This happened a day after my cousin installed a radio in the car, it previously did not have one and had the harness cut. Could something have shorted? because now the light has not come on at all in 2 days
#199 of 208 3 cylinder to 4 by buzz11 Sep 08, 2009 (2:52 pm)
is it possible to swap a 96 4 cylinder and drop it into a 98 with a 3 cylinder
#200 of 208 93 geo metro by curt16 Sep 16, 2009 (9:46 am)
I'm looking at buying a 93 metro but it has low compression in the third hole is this a burnt valve and how would I check this or does it just need a new motor

#202 of 208 '92 3-cyl into a '95 by handiman47 Sep 21, 2009 (5:24 pm)
I need to replace to 3 cylinder engine of my '95. Will a 3-cylinder and trany from a '92 drop right in or do I need to bring along the cv axles, hub-knuckle assemblies, and struts?
#203 of 208 2001 Metro ingnition problem by amontyg Oct 07, 2009 (7:13 am)
Bought the car a year ago and had to replace the fuel module to get it running, and it has been running strong, however occasionally the fuel pump will not come on and bring the fuel system to pressure when the ignition is turned on. The way i get around this is simply to turn the key back and fourth four or five times and eventually the pump will kick on. The pump corresponds with the check engine light. in other words when the pump is not working the check engine light will not come on before the car is started and when the pump does work the check engine light will come on and turn off as soon as the car started. this is what makes me think it is an ignition problem. possibley a switch somewhere? have any of you encountered this before? or at least what is your guess at what the problem is?
#204 of 208 1990 Geo Metro Convertable Engine Will Not Start. by cj7jeeper Nov 09, 2009 (5:49 pm)
My son limped home my Geo and it has not started since. It cranks, all cylinders have good pressure, Have fuel no spark. Tested Coil and it reads good. I do not have a crank P/U. The distributor pick-up coil test good, The distributor ignitor may be the problem...I am unable to check at this time and can't find info on how to test. Is there anything else that I could check before I buy parts? Replies to this message: zaken1 (Nov 14, 2009 12:36 am)
