Replying to: m564ag (Oct 31, 2006 4:47 am) With the timing marks - watch out for set up. Is different before 1992 and after 1993 up. What yer is your car? YOu shuold't pump more than 28 psi in the tires. You will shake to much the car, if you have more pressure. All car will vibrate on higher tire pressure. I use 13" tires. Before 1992 the sepc are 10 BTDC, but after 1993 July up, the timing is only 5 BTDC, but you must lock the timing on plastic plug ( bridge two outlets with wire). |

Hey, I'm new here, hope someone can give me an answer. I have a 91 Geo metro, Car runs great but has hesitant acceleration at speed. If it were a carburated car I'd say the accelerator pump was not working. But since this is EFI I'm lost. Anyone have this same problem or know what is wrong? Many Thanks Ron |

Could be a number of things: spark (did you change the plugs recently?), catalyzer could be plugged up...

Replying to: vanillalatte (Oct 31, 2006 3:13 pm) What I did - remove the Catal. Converter, cut of the front pipe and I cleaned the converter inside. Removed all "honey nest". Installed back and never have any problem. My OX. sensor work better, no more back pressure, better mpg. Passed emission - easy. Just do not mention about that. Pipeman |

Well.....it's not legal really, we are well aware of that. BUT you get better gas mileage, thus you are more efficient, therefore you pollute less......

Replying to: geometro91 (Nov 05, 2006 11:18 am) Second. Remove the exhaust manifold. After the exhaust manifold is out - clean very well the opening ( 1/2" dia.) accross the cyl.head. From the exhaust to the egr. Look at the exhuast minifold and you will see small hole running between the "exhaust collectors" 1 - 2 -3. The opening is less than 1/8" dia. Use the transmission fluis to clean the passages. Put the one site of the pipe cleaner to the transm. fliud and insert in every small hole. Must go thru. If is plugged, put more transm. fliud in the openong in leave for 15 min. and try push thru. If will not open the hole, use some sharp wire and push. By gental to nor brake the wire. Also you can use high pressure air to clean the passages. Replace all bolts with studs. Easy to work. Use grade 9 or 10 studs. Open the ehaust manifold inlets abut 45 degree angle , the flow will be easier. Before instaling the studs, retap the thread in the cyl. head with greas. Use copper grease to install the studs in the cyl. head. Any questions, let me know. Pipeman - visit my web www.bacartpipes.com

Replying to: pipeman (Nov 05, 2006 4:21 pm) No sure what you mean by opening up the inlets on the exhaust manifold. Are you talking about taking a die grinder to the manifold itself? If so how far back should the 45 degree bevel go? Thanks, geometro91
