Please, if you are asking for help with diagnostics, do everyone a favor and list the make, model, year, trans type, engine type, modifications, etc of your car when asking questions about it. Most of us aren't mind readers (although some of us may play one on tv). It will help you get the help you need faster and keep me from asking so many questions and increasing my post count unnecessarily. I think we need a standard format for questions.

year:
make:
model:
mileage:
trans type:
recent maintenance:
recent modifications:
other modifications:

Something like that will help everyone out that is trying to help you. So, please take the time when writing your post to include this much needed information. All of your friends might know what you drive... but we're not your friends :P

i have a 1998 base and on the engine it says ECI-MULTI 3000 and its fwd idk if its a dohc or a sohc but is what i have good?

if its a 98 bse then you have the 166 Horse SOHC engine. also you can tell if you have 2 valve covers (1 right in front that is labeled "24 Valve something or other" and another under your intake manifold)

but i'll guarentee its a SOHC...... (sorry for the bad news)
